Quasi elastic scattering of ν-bar_μ ¹²C

Neutrinos are elementary particles with no electric charge, no magnetic moment, half integral spin and a small but non-zero mass. Being electrically neutral, neutrinos rarely interact with matter via weak force. In this work, we study charged current anti-neutrino - nucleus (¹²C) QES. To describe CCQES, we use the Llewellyn Smith (LS) model. For incorporating the nuclear effects, we use the Fermi gas model along with Pauli suppression condition. We calculate ν-bar_μ ¹²C CCQES differential and total cross sections for different values of axial mass M_A and compare the results with experimental data, with the goal of finding the most appropriate M_A value
