Nuclear effects on lepton polarization in charged-current quasielastic neutrino scattering
نویسندگان
چکیده
We use a correlated local Fermi gas (LFG) model, which accounts also for long distance corrections of the RPA type and final-state interactions, to compute the polarization of the final lepton in charged-current quasielastic neutrino scattering. The present model has been successfully used in recent studies of inclusive neutrino nucleus processes and muon capture. We investigate the relevance of nuclear effects in the particular case of τ polarization in tau-neutrino induced reactions for several kinematics of relevance for neutrino oscillation experiments. © 2006 Elsevier B.V.

Nuclear model effects in Charged Current neutrino–nucleus quasielastic scattering
The quasielastic scattering of muon neutrinos on oxygen 16 and carbon 12 targets is studied for neutrino energies between 200 MeV and 1 GeV, using the relativistic Fermi gas and a relativistic shell model. Final state interactions are included within the distorted wave impulse approximation. The different models are then employed to compute the inclusive charged–current quasielastic cross secti...
متن کاملNuclear model effects in neutrino-nucleus quasielastic scattering
Nuclear model effects in neutrino-nucleus quasielastic scattering are studied within the distorted wave impulse approximation, using a relativistic shell model to describe the nucleus, and comparing it with the relativistic Fermi gas. Both charged-current and neutral-current processes are considered and, for the neutral-current case, the uncertainties that nuclear effects may introduce in measu...
متن کاملRelativistic nuclear structure effects in quasielastic neutrino scattering.
Charged-current cross sections are calculated for quasielastic neutrino and antineutrino scattering using a relativistic meson-nucleon model. We examine how nuclear-structure effects, such as relativistic random-phaseapproximation (RPA) corrections and momentum-dependent nucleon selfenergies, influence the extraction of the axial form factor of the nucleon. RPA corrections are important only at...
متن کاملFirst Measurement of Muon Neutrino Charged Current Quasielastic (CCQE) Double Differential Cross Section
Using a high statistics sample of muon neutrino charged current quasielastic (CCQE) events, we report the first measurement of the double differential cross section ( d 2σ dTμ d cos θμ ) for this process. The result features reduced model dependence and supplies the most complete information on neutrino CCQE scattering to date. Measurements of the absolute cross section as a function of neutrin...
متن کاملNuclear Effects in the F3 Structure Function
Experiments on deep-inelastic scattering (DIS) of charged leptons and neutrino remains an important source of information about the nucleon as well as about the nuclear structure. DIS experiments with neutrino beams 1,2 has reached now an accuracy comparable to that of experiments with charged leptons. Note in this respect that because of statistics reasons neutrino data are collected for heavy...
