A relativistic model for neutrino pion production from nuclei in the resonance region
نویسنده
چکیده
We present a relativistic model for electroweak pion production from nuclei, focusing on the ∆ and the second resonance region. Bound states are derived in the Hartree approximation to the σ − ω Walecka model. Final-state interactions of the outgoing pion and nucleon are described in a factorized way by means of a relativistic extension of the Glauber model. Our formalism allows a detailed study of neutrino pion production through Q2, W , energy, angle and out-of-plane distributions.

Single Pion Production in Neutrino Reactions and Estimates for Charge - Exchange Effects
We calculate single pion production by neutrinos in the resonance region. We consider both charged and neutral current reactions on free protons and neutrons. We present differential and total cross sections which can be compared with experiments. Then we use these results to calculate the spectra of the emerging pions including the Pauli suppression factor and rescattering corrections for reac...

We present a model for neutrino-nucleus scattering in the energy region relevant for present and forthcoming neutrino-oscillation experiments. The model is based on the RPA treatment of the nuclear responses in the quasi-elastic and Delta-resonance region. It includes also in a phenomenological way nucleon knock-out. It aims at the description, within a single framework, of several final state ...
متن کاملDynamical Model of Coherent Electroweak Pion Production Reactions on Nuclei
We have developed a dynamical model for a unified description of the pion-nucleus scattering and photoand neutrino-induced coherent pion production on nuclei. Our approach is based on a combined use of the Sato-Lee model for the electroweak pion production on a single nucleon and the ∆-hole model of pion-nucleus scattering. Numerical calculations are carried out for the case of the 12C target. ...
متن کاملNeutrino-induced meson productions
We develop a dynamical coupled-channels (DCC) model for neutrino-nucleon reactions in the resonance region, by extending the DCC model that we have previously developed through an analysis of πN, γN → πN, ηN, KΛ, KΣ reaction data for W ≤ 2.1 GeV. We analyze electron-induced reaction data for both proton and neutron targets to determine the vector current form factors up to Q2 ≤ 3.0 (GeV/c)2. Ax...

Although charged leptons, contrary to neutrinos, cannot oscillate, exploring whether a coherent superposition of charged lepton states can change to others during the propagation is an important problem in the neutrino oscillation theory. In this paper, we consider electrons and muons coming from the pions and W decays and study their propagation in relativistic Bohmian quantum mechanics. We f...
