Further Studies of Transverse Enhancement in Quasielastic Electron Scattering

Abstract

In a previous communication we reported on a parametrization of the observed enhancement in the transverse electron quasielastic (QE) response function for nucleons bound in carbon as a function of the square of the four momentum transfer ($Q^2$) in terms of a correction to the magnetic form factors of bound nucleons. That parametrization was used to predict the overall magnitude and $Q^2$ dependence of the cross section for neutrino quasielastic scattering on nuclear targets. In this paper, we extend the study to include parametrizations of both the $Q^2$ as well as the energy transfer ($\nu$) dependence of the transverse enhancement. These parametrization can be used to give a more complete two dimensional description of the neutrino quasielastic scattering process on nuclear targets, which is essential for precision studies of mass splitings and mixing angles in neutrino oscillation experiments.
