Relativistic models for quasielastic neutrino scattering
Abstract
We present quasielastic neutrinonucleus cross sections in the energy range from 150 MeV to 5 GeV for the target nuclei {sup 12}C and {sup 56}Fe. A relativistic description of the nuclear dynamics and the neutrinonucleus coupling is adopted. For the treatment of finalstate interactions we rely on two frameworks successfully applied to exclusive electronnucleus scattering: a relativistic optical potential and a relativistic multiplescattering Glauber approximation. At lower energies, the opticalpotential approach is considered to be the optimum choice, whereas at high energies a Glauber approach is more natural. Comparing the results of both calculations, it is found that the Glauber approach yields valid results down to the remarkably small nucleon kinetic energies of 200 MeV. We argue that the nuclear transparencies extracted from A(e,e{sup '}p) measurements can be used to obtain realistic estimates of the effect of FSI mechanisms on quasielastic neutrinonucleus cross sections. We present two independent relativistic planewave impulse approximation (RPWIA) calculations of quasielastic neutrinonucleus cross sections. They agree at the percentage level, showing the reliability of the numerical techniques adopted and providing benchmark RPWIA results.

Chargedcurrent cross sections are calculated for quasielastic neutrino and antineutrino scattering using a relativistic mesonnucleon model. We examine how nuclearstructure effects, such as relativistic randomphaseapproximation (RPA) corrections and momentumdependent nucleon selfenergies, influence the extraction of the axial form factor of the nucleon. RPA corrections are important only at lowmomentum transfers. In contrast, the momentum dependence of the relativistic selfenergies changes appreciably the value of the axialmass parameter {ital M}{sub {ital A}} extracted from dipole fits to the axial form factor. Using Brookhaven`s experimental neutrino spectrum we estimate the sensitivity of {ital M}{sub {ital A}} to various relativistic nuclearstructure effects.

Superscaling in Charged Current Neutrino Quasielastic Scattering in the Relativistic Impulse Approximation
Superscaling of the quasielastic cross section in chargedcurrent neutrinonucleus reactions at energies of a few GeV is investigated within the framework of the relativistic impulse approximation. Several approaches are used to describe finalstate interactions and comparisons are made with the planewave approximation. Superscaling is very successful in all cases. The scaling function obtained using a relativistic mean field for the final states shows an asymmetric shape with a long tail extending towards positive values of the scaling variable, in excellent agreement with the behavior presented by the experimental scaling function. 
Finalstate interactions and superscaling in the semirelativistic approach to quasielastic electron and neutrino scattering
The semirelativistic approach to electron and neutrino quasielastic scattering from nuclei is extended to include finalstate interactions. Starting with the usual nonrelativistic continuum shell model, the problem is relativized by using the semirelativistic expansion of the current in powers of the initial nucleon momentum and relativistic kinematics. Two different approaches are considered for the finalstate interactions: the SmithWambach 2p2h damping model and the Diracequationbased potential extracted from a relativistic meanfield plus the Darwin factor. Using the latter, the scaling properties of (e,e{sup '}) and ({nu}{sub {mu}},{mu}{sup }) cross sections for intermediate momentum transfers are investigated. 
Superscaling and neutral current quasielastic neutrinonucleus scattering beyond the relativistic Fermi gas model
The superscaling analysis is extended to include quasielastic (QE) scattering via the weak neutral current (NC) of neutrinos and antineutrinos from nuclei. The scaling function obtained within the coherent density fluctuation model (CDFM) [used previously in calculations of QE inclusive electron and chargechanging (CC) neutrino scattering] is applied to neutral current neutrino and antineutrino scattering with energies of 1 GeV from {sup 12}C with a proton and neutron knockout (uchannel inclusive processes). The results are compared with those obtained using the scaling function from the relativistic Fermi gas model and the scaling function as determined from the superscaling analysis (SuSA)more » 
Relativistic descriptions of quasielastic chargedcurrent neutrinonucleus scattering: Application to scaling and superscaling ideas
The analysis of the recent experimental data on chargedcurrent neutrinonucleus scattering cross sections measured at MiniBooNE requires relativistic theoretical descriptions also accounting for the role of finalstate interactions. In this work we evaluate inclusive quasielastic differential neutrino cross sections within the framework of the relativistic impulse approximation. Results based on the relativistic meanfield potential are compared with the ones corresponding to the relativistic Green'sfunction approach. An analysis of scaling and superscaling properties provided by both models is also presented.
