“…However, since for PV electron scattering we require only the transverse projections of the axial-vector current, which do not include the pseudoscalar contributions, the latter are not needed in the present work. For purely weak interaction processes, and then only when mass terms must be retained, is it necessary to include such contributions (see, for example, [36]). …”

Parity-conserving and -violating response functions are computed for the inclusive electroexcitation of the N * (1440) (Roper) resonance in nuclear matter modeled as a relativistic Fermi gas. Using various empirical parameterizations and theoretical models of the N − N * (1440) transition form factors, the sensitivity of the response functions to details of the structure of the Roper resonance is investigated. The possibility of disentangling this resonance from the contribution of ∆ electroproduction in nuclei is addressed. Finally, the contributions of the Roper resonance to the longitudinal scaling function and to the Coulomb sum rule are also explored.

The methods used in the evaluation of the neutrino-nucleus cross section are reviewed. Results are shown for a variety of targets of practical importance. Many of the described reactions are accessible in future experiments with neutrino sources from the pion and muon decays at rest, which might be available at the neutron spallation facilities. Detailed comparison between the experimental and theoretical results would establish benchmarks needed for verification and/or parameter adjustment of the nuclear models. Having a reliable tool for such calculation is of great importance in a variety of applications, e.g. the neutrino oscillation studies, detection of supernova neutrinos, description of the neutrino transport in supernovae and description of the r-process nucleosynthesis.

Abstract.We investigate isospin mixing effects in the asymmetry as obtained in parity-violating electron scattering from 4 He, 12 C, 48 Ca, 90 Zr and 208 Pb nuclei. The scattering analysis is developed within the distorted wave Born approximation (DWBA) accounting for nucleon form factors. We use a relativistic mean field model, including the σ, ω, ρ and δ mesons, with density dependent couplings, as well as the electromagnetic interaction . Numerical results are presented for the asymmetry, charge and weak charge radius.
