Charged current quasi-elastic scattering of νμ off 12C

Abstract

In this work, we study charged current quasi-elastic scattering (QES) of vμ off nucleon and nucleus using a formalism based on the Llewellyn Smith (LS) model. Parameterizations by Galster et al. are used for electric and magnetic Sach'fs form factors of the nucleons. We use the Fermi gas model along with the Pauli suppression condition to take into account the nuclear effects in the anti-neutrino.nucleus QES. We calculate vμ - p and vμ - 12C charged current quasi-elastic scattering differential and total cross sections for different values of axial mass MA, and compare the results with data from the GGM, SKAT, BNL, NOMAD, MINERA and MiniBooNE experiments. The present theoretical approach gives a good description of differential cross section data. The calculations with axial mass MA=0.979 and 1.05 GeV are compatible with data from most of the experiments. © 2018 Chinese Physical Society and the Institute of High Energy Physics of the Chinese Academy of Sciences and the Institute of Modern Physics of the Chinese Academy of Sciences and IOP Publishing Ltd.
