“…Whereas most of the existing calculations refer to a 12 C target [13,15,[26][27][28][29][30][31][32][33], there is growing interest in the extension to heavier nuclei, such as 16 O, 40 Ar, 56 Fe, and 208 Pb, used in ongoing and future neutrino experiments. Since the calculation of the 2p-2h response is computationally demanding and time consuming, in this paper we provide an estimate of the density dependence of these contributions which can be used to extrapolate the results from one nucleus to another.…”

“…The description based on the IA and the spectral function formalism [12] has been successful in describing inclusive electronscattering data in a variety of kinematic regimes [13][14][15] and has recently been be extended to the analysis of neutrino scattering [16][17][18][19]. However, due to the scarcity of available inclusive cross sections for argon and titanium, theoretical models of nuclear effects in electroweak interactions [20][21][22][23][24][25][26] cannot be currently validated in the kinematical region relevant for neutrino experiments.…”

To probe CP violation in the leptonic sector using GeV energy neutrino beams in current and future experiments using argon detectors, precise models of the complex underlying neutrino and antineutrino interactions are needed. The E12-14-012 experiment at Jefferson Lab Hall A was designed to perform a combined analysis of inclusive and exclusive electron scatterings on both argon (N = 22) and titanium (Z = 22) nuclei using GeV-energy electron beams. The measurement on titanium nucleus provides essential information to understand the neutrino scattering on argon, large contribution to which comes from scattering off neutrons. Here we report the first experimental study of electron-titanium scattering as double-differential cross section at beam energy E = 2.222 GeV and electron-scattering angle θ = 15.541• , measured over a broad range of energy transfer, spanning the kinematical regions in which quasielastic scattering and delta production are the dominant reaction mechanisms. The data provide valuable new information needed to develop accurate theoretical models of the electromagnetic and weak cross sections of these complex nuclei in the kinematic regime of interest to neutrino experiments.

Abstract. We present a study on the charge current quasi elastic scattering of ν µ from nucleon and nuclei which gives a charged muon in the final state. To describe nuclei, the Fermi Gas model has been used with proposed Pauli suppression factor. The diffuseness parameter of the Fermi distribution has been obtained using experimental data. We also investigate different parametrizations for electric and magnetic Sach's form factors of nucleons. Calculations have been made for CCQES total and differential cross sections for the cases of ν µ − N , ν µ − 12 C and ν µ − 56 F e scatterings and are compared with the data for different values of the axial mass. The present model gives excellent description of measured differential cross section for all the systems.
