A primary trisomic for chromosome 3 in a 6-rowed barley
(1973) K. Das; S.C. Kundu
The trisomic plant isolated from gamma-irradiated barley material was phenotypically different from the normal diploid. The leaves of the trisome were narrow, margins rolled and light green in colour. Ear heads were also short, narrow and irregular. Ovule sterility (42.88 per cent) was relatively higher than pollen sterility (23.47 per cent). Cytological examination at metaphase I revealed 6II+1III, 7II, +1I and 6II+3I. The trivalents were chains of 3 and V, Y, frying pan and Q shaped indicating it to be a primary trisomic. The trisome was crossed with a set of translocation homozygotes and the cytology of the F1 hybrids was studied. This revealed that it was a trisomic for chromosome 3. However, the present trisomic looked different from the pale trisomic for chromosome 3 described by Tsuchiya in 2-rowed barley. Trisomics occurred more frequently in the progeny of smaller seeds of trisomic plants. Transmission rate of the extra chromosome through ovule was high while it was nil through pollen. © 1973, Japan Mendel Society, International Society of Cytology. All rights reserved.
A primary Trisomic for Chromosome 4 in a Six-Rowed Barley
(1971) K. Das; G. Bhowmik
A primary trisomic was isolated in M3 from a population of thermal neutron irradiated 6-rowed cultivated barley K 12. Karyotypic study has revealed that the extrachromosome is chromosome 4. The present trisomic for chromosome 4 is morphologically distinct from the trisomic for the same chromosome in 2-rowed wild and cultivated barley described by Tsuchiya. © 1971, Japan Mendel Society, International Society of Cytology.

Additional Evidences of Cytogenetic Differentiation in Certain Linum Species with 2n=30 Chromosomes
(1982) M. Rai; K. Das
Meiotic studies in Linum usitatissimum L., Linum angustifolium Huds. and Linum africanum L. were carried out and 2n=30 chromosome number was confirmed. Among the 3 species, mean chiasmata per bivalent varied between 1.82 to 1.90 maximum being in Linum africanum. Secondary association of chromosomes were observed in Linum usitatissimum as well as in Linum angustifolium. However, the 2 species differed in number of bivalents associated. In Linum angustifolium as many as 8 bivalents were involved in association where as in Linum usitatissimum not more than 4 bivalents participated in such a association. In both the species, 11 II+2 IV configuration was most frequent. In all the species early separation of chromosomes in 1-3 bivalents was noted. In Linum angustifolium one of the secondarily associated bivalent invariable showed early separation. Despite secondary association and early separation, meiosis was normal in all the species. Pollen and ovule fertility was also normal. Cytological data in general revealed cryptic chromosomal differences among the 3 species. Linum angustifolium appeared closer to Linum usitatissimum than to Linum africanum. © 1982, Japan Mendel Society, International Society of Cytology. All rights reserved.

Deuteron-gold (d+Au) collisions at the Relativistic Heavy Ion Collider provide ideal platforms for testing QCD theories in dense nuclear matter at high energy. In particular, models suggesting strong saturation effects for partons carrying small nucleon momentum fraction (x) predict modifications to jet production at forward rapidity (deuteron-going direction) in d+Au collisions. We report on two-particle azimuthal angle correlations between charged hadrons at forward/backward (deuteron/gold going direction) rapidity and charged hadrons at midrapidity in d+Au and p+p collisions at sNN=200GeV. Jet structures observed in the correlations are quantified in terms of the conditional yield and angular width of away-side partners. The kinematic region studied here samples partons in the gold nucleus with x∼0.1 to ∼0.01. Within this range, we find no x dependence of the jet structure in d+Au collisions. © 2006 The American Physical Society.

The azimuthal anisotropy coefficients v2 and v4 of π0 and η mesons are measured in Au + Au collisions at sNN=200 GeV as a function of transverse momentum pT (1-14 GeV/c) and centrality. The extracted v2 coefficients are found to be consistent between the two meson species over the measured pT range. The ratio of v4/v22 for π0 mesons is found to be independent of pT for 1-9 GeV/c, implying a lack of sensitivity of the ratio to the change of underlying physics with pT. Furthermore, the ratio of v4/v22 is systematically larger in central collisions, which may reflect the combined effects of fluctuations in the initial collision geometry and finite viscosity in the evolving medium. © 2013 American Physical Society.

Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled p+p collisions. These measurements indicate that charm and bottom quarks interact with the hot dense matter produced in heavy-ion collisions much more than expected. Here we extend these studies to two-particle correlations where one particle is an electron from the decay of a heavy-flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interactions between heavy quarks and the matter, such as whether the modification of the away-side-jet shape seen in hadron-hadron correlations is present when the trigger particle is from heavy-meson decay and whether the overall level of away-side-jet suppression is consistent. We statistically subtract correlations of electrons arising from background sources from the inclusive electron-hadron correlations and obtain two-particle azimuthal correlations at √sNN=200 GeV between electrons from heavy-flavor decay with charged hadrons in p+p and also first results in Au+Au collisions. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to p+p collisions. © 2011 American Physical Society.

Charged-pion-interferometry measurements were made with respect to the second- and third-order event plane for Au + Au collisions at √sNN200 GeV. A strong azimuthal-angle dependence of the extracted Gaussian-source radii was observed with respect to both the second- and third-order event planes. The results for the second-order dependence indicate that the initial eccentricity is reduced during the medium evolution, which is consistent with previous results. In contrast, the results for the third-order dependence indicate that the initial triangular shape is significantly reduced and potentially reversed by the end of the medium evolution, and that the third-order oscillations are largely dominated by the dynamical effects from triangular flow. © 2014 American Physical Society

The PHENIX collaboration presents first measurements of low-momentum (0.41 GeV/c) direct-photon yield dNγdir/dη is a smooth function of dNch/dη and can be well described as proportional to (dNch/dη)α with α≈1.25. This scaling behavior holds for a wide range of beam energies at the Relativistic Heavy Ion Collider and the Large Hadron Collider, for centrality selected samples, as well as for different A+A collision systems. At a given beam energy, the scaling also holds for high pT (>5 GeV/c), but when results from different collision energies are compared, an additional sNN-dependent multiplicative factor is needed to describe the integrated-direct-photon yield. © 2019 authors.

High-energy proton- and deuteron-nucleus collisions provide an excellent tool for studying a wide array of physics effects, including modifications of parton distribution functions in nuclei, gluon saturation, and color neutralization and hadronization in a nuclear environment, among others. All of these effects are expected to have a significant dependence on the size of the nuclear target and the impact parameter of the collision, also known as the collision centrality. In this article, we detail a method for determining centrality classes in p(d)+A collisions via cuts on the multiplicity at backward rapidity (i.e., the nucleus-going direction) and for determining systematic uncertainties in this procedure. For d+Au collisions at sNN=200 GeV we find that the connection to geometry is confirmed by measuring the fraction of events in which a neutron from the deuteron does not interact with the nucleus. As an application, we consider the nuclear modification factors Rp(d)+A, for which there is a bias in the measured centrality-dependent yields owing to auto correlations between the process of interest and the backward-rapidity multiplicity. We determine the bias-correction factors within this framework. This method is further tested using the hijing Monte Carlo generator. We find that for d+Au collisions at sNN=200 GeV, these bias corrections are small and vary by less than 5% (10%) up to pT=10 (20) GeV/c. In contrast, for p+Pb collisions at sNN=5.02 TeV we find that these bias factors are an order of magnitude larger and strongly pT dependent, likely attributable to the larger effect of multiparton interactions. © 2014 American Physical Society.

We present transverse momentum (pT) spectra of charged hadrons measured in deuteron-gold and nucleon-gold collisions at sNN=200 GeV for four centrality classes. Nucleon-gold collisions were selected by tagging events in which a spectator nucleon was observed in one of two forward rapidity detectors. The spectra and yields were investigated as a function of the number of binary nucleon-nucleon collisions, ν, suffered by deuteron nucleons. A comparison of charged particle yields to those in p+p collisions show that yield per nucleon-nucleon collision saturates with ν for high momentum particles. We also present the charged hadron to neutral pion ratios as a function of pT. © 2008 The American Physical Society.

The PHENIX experiment at RHIC has measured the centrality dependence of the direct photon yield from Au+Au collisions at sNN=200 GeV down to pT=0.4 GeV/c. Photons are detected via photon conversions to e+e- pairs and an improved technique is applied that minimizes the systematic uncertainties that usually limit direct photon measurements, in particular at low pT. We find an excess of direct photons above the Ncoll-scaled yield measured in p+p collisions. This excess yield is well described by an exponential distribution with an inverse slope of about 240MeV/c in the pT range 0.6-2.0 GeV/c. While the shape of the pT distribution is independent of centrality within the experimental uncertainties, the yield increases rapidly with increasing centrality, scaling approximately with Npartα, where α=1.38±0.03(stat)±0.07(syst). © 2015 American Physical Society.

The dependence of transverse momentum spectra of neutral pions and η mesons with pT<16GeV/c and pT<12GeV/c, respectively, on the centrality of the collision has been measured at midrapidity by the PHENIX experiment at the BNL Relativistic Heavy Ion Collider (RHIC) in d+Au collisions at sNN=200GeV. The measured yields are compared to those in p+p collisions at the same sNN scaled by the number of underlying nucleon-nucleon collisions in d+Au. At all centralities, the yield ratios show no suppression, in contrast to the strong suppression seen for central Au+Au collisions at RHIC. Only a weak pT and centrality dependence can be observed. © 2007 The American Physical Society.

Jet production rates are measured in p+p and d+Au collisions at sNN=200 GeV recorded in 2008 with the PHENIX detector at the Relativistic Heavy Ion Collider. Jets are reconstructed using the R=0.3 anti-kt algorithm from energy deposits in the electromagnetic calorimeter and charged tracks in multiwire proportional chambers, and the jet transverse momentum (pT) spectra are corrected for the detector response. Spectra are reported for jets with 12

A comprehensive survey of event-by-event fluctuations of charged hadron multiplicity in relativistic heavy ions is presented. The survey covers Au+Au collisions at sNN=62.4 and 200 GeV, and Cu+Cu collisions at sNN=22.5,62.4, and 200 GeV. Fluctuations are measured as a function of collision centrality, transverse momentum range, and charge sign. After correcting for nondynamical fluctuations due to fluctuations in the collision geometry within a centrality bin, the remaining dynamical fluctuations expressed as the variance normalized by the mean tend to decrease with increasing centrality. The dynamical fluctuations are consistent with or below the expectation from a superposition of participant nucleon-nucleon collisions based upon p+p data, indicating that this dataset does not exhibit evidence of critical behavior in terms of the compressibility of the system. A comparison of the data with a model where hadrons are independently emitted from a number of hadron clusters suggests that the mean number of hadrons per cluster is small in heavy ion collisions. © 2008 The American Physical Society.

Bose-Einstein correlations of charged kaons are used to probe Au+Au collisions at sNN=200GeV and are compared to charged pion probes, which have a larger hadronic scattering cross section. Three-dimensional Gaussian source radii are extracted, along with a one-dimensional kaon emission source function. The centrality dependences of the three Gaussian radii are well described by a single linear function of Npart1/3 with a zero intercept. Imaging analysis shows a deviation from a Gaussian tail at r10fm, although the bulk emission at lower radius is well described by a Gaussian. The presence of a non-Gaussian tail in the kaon source reaffirms that the particle emission region in a heavy-ion collision is extended, and that similar measurements with pions are not solely due to the decay of long-lived resonances. © 2009 The American Physical Society.

We present a new analysis of J/ψ production yields in deuteron-gold collisions at sNN=200 GeV using data taken from the PHENIX experiment in 2003 and previously published in S. S. Adler [Phys. Rev. Lett 96, 012304 (2006)]. The high statistics proton-proton J/ψ data taken in 2005 are used to improve the baseline measurement and thus construct updated cold nuclear matter modification factors (RdAu). A suppression of J/ψ in cold nuclear matter is observed as one goes forward in rapidity (in the deuteron-going direction), corresponding to a region more sensitive to initial-state low-x gluons in the gold nucleus. The measured nuclear modification factors are compared to theoretical calculations of nuclear shadowing to which a J/ψ (or precursor) breakup cross section is added. Breakup cross sections of σbreakup=2.8-1. 4+1.7 (2.2-1.5+1.6) mb are obtained by fitting these calculations to the data using two different models of nuclear shadowing. These breakup cross-section values are consistent within large uncertainties with the 4.2±0.5 mb determined at lower collision energies. Projecting this range of cold nuclear matter effects to copper-copper and gold-gold collisions reveals that the current constraints are not sufficient to firmly quantify the additional hot nuclear matter effect. © 2008 The American Physical Society.

We present measurements of J/ψ yields in d+Au collisions at √sNN=200GeV recorded by the PHENIX experiment and compare them with yields in p+p collisions at the same energy per nucleon-nucleon collision. The measurements cover a large kinematic range in J/ψ rapidity (-2.2
