The phenomenon of superscaling for quasielastic lepton induced reactions at energies of a few GeV is investigated within the framework of the relativistic impulse approximation. A global analysis of quasielastic inclusive electron and charged-current neutrino scattering reactions on nuclei is presented. Scaling and superscaling properties are...

A detailed study of the electromagnetic responses for quasielastic (e, e) reactions from nuclear matter is presented within the framework of a relativistic model including momentum dependent scalar and vector mean field potentials in both the initial and final nucleon wave function states. The effects ascribed to the use of energy-dependent...

A study of the cross section for chaged-current quasielastic (CCQE) scattering on nuclei has been performed using a description of nuclear dynamics based on the Relativistic Fermi Gas model (RFG). The role played by different parametrizations for the weak nucleon form factors is analyzed taking into account the relevance of the axial mass...

It is well known that coincidence quasielastic (e′N) reactions are not appropriate to analyze effects linked to parity violation due the presence of the fifth electromagnetic response RTL′. Nevertheless, in this work we develop a fully relativistic approach to be applied to parity-violating (PV) quasielastic (e′N) processes. This is of...

We study parity violation in quasielastic electron-nucleus scattering using the relativistic impulse approximation. Different fully relativistic approaches have been considered to estimate the effects associated with the final-state interactions. We have computed the parity-violating quasielastic (PVQE) asymmetry and have analyzed its...

An analysis of the effects of meson exchange and isobar currents in exclusive (e,e′p) processes from 16O under quasifree kinematics is presented. A model that has probed its feasibility for inclusive quasielastic (e,e′) processes is considered. Sensitivity to final state interactions between the outgoing proton and the residual nucleus is...

We perform a statistical analysis of the full set of parity-violating asymmetry data for elastic electron scattering including the most recent high precision measurement from Q-weak. Given the basis of the present analysis, our estimates appear to favor nonzero vector strangeness, specifically, positive (negative) values for the electric...

A study of the effects of meson-exchange currents and isobar configurations in A(e,e'p)B reactions is presented. We use a distorted wave impulse approximation model where final-state interactions are treated through a phenomenological optical potential. The model includes relativistic corrections in the kinematics and...
