    Revisiting νμ(νˉμ)\nu_\mu(\bar\nu_\mu) and νe(νˉe)\nu_e(\bar\nu_e) Induced Quasielastic Scattering from Nuclei in Sub-GeV Energy Region

    We present the results of charged current quasielastic(CCQE) scattering cross sections from free as well as bound nucleons like in 12C^{12}C, 16O^{16}O, 40Ar^{40}Ar and 208Pb^{208}Pb nuclear targets in Eν(νˉ) ≤ E_\nu(_{\bar\nu})~\le~ 1 GeV energy region. The results are obtained using local Fermi gas model with and without RPA effect. The differences those may arise in the electron and muon production cross sections due to the different lepton mass, uncertainties in the axial dipole mass MAM_A and pseudoscalar form factor, and due to the inclusion of second class currents have been highlighted for neutrino/antineutrino induced processes.Comment: Published in Journal of the Physical Society of Japan (NuInt-2015

    Weak Kaon Production off the Nucleon

    The weak kaon production off the nucleon induced by neutrinos is studied at the low and intermediate energies of interest for some ongoing and future neutrino oscillation experiments. This process is also potentially important for the analysis of proton decay experiments. We develop a microscopical model based on the SU(3) chiral Lagrangians. The basic parameters of the model are fpi, the pion decay constant, Cabibbo's angle, the proton and neutron magnetic moments and the axial vector coupling constants for the baryons octet, D and F, that are obtained from the analysis of the semileptonic decays of neutron and hyperons. The studied mechanisms are the main source of kaon production for neutrino energies up to 1.2 to 1.5 GeV for the various channels and the cross sections are large enough to be amenable to be measured by experiments such as Minerva and T2K

    Weak Production of Strange Particles and η\eta Mesons off the Nucleon

    Full text link
    The strange particle production induced by (anti)neutrino off nucleon has been studied for ∣ΔS∣=0|\Delta S|=0 and ∣ΔS∣=1|\Delta S|=1 channels. The reactions those we have considered are for the production of single kaon/antikaon, eta and associated particle production processes. We have developed a microscopical model based on the SU(3) chiral Lagrangian. The basic parameters of the model are fπf_\pi, the pion decay constant, Cabibbo angle, the proton and neutron magnetic moments and the axial vector coupling constants for the baryons octet. For antikaon production we have also included Σ∗\Sigma^*(1385) resonance and for eta production S11S_{11}(1535) and S11S_{11}(1650) resonances are included.Comment: To appear in AIP Conf.

    Antineutrino induced antikaon production off the nucleon

    Full text link
    The charged current antikaon production off nucleons induced by antineutrinos is studied at low and intermediate energies. We extend here our previous calculation on kaon production induced by neutrinos. We have developed a microscopic model that starts from the SU(3) chiral Lagrangians and includes background terms and the resonant mechanisms associated to the lowest lying resonance in the channel, namely, the Sigma*(1385). Our results could be of interest for the background estimation of various neutrino oscillation experiments like MiniBooNE and SuperK. They can also be helpful for the planned antineutrino experiments like MINERvA, NOvA and T2K phase II and for beta-beam experiments with antineutrino energies around 1 GeV.Comment: 15 pages and 6 figures.

    Charged lepton induced one kaon production off the nucleon

    We study single kaon production off the nucleon induced by electrons (positrons) i.e., e(-) (e(+)) + N -> v(e) ((v) over bar (e)) + (K) over bar (K) + N' at low energies. The possibility of observing these processes with the high luminosity beams available at TJNAF and Mainz is discussed, taking into account that the strangeness conserving electromagnetic reactions have a higher energy threshold for (K) over bar (K) production. The calculations are done using a microscopic model that starts from the SU(3) chiral Lagrangians and includes background terms and the resonant mechanisms associated to the lowest lying resonance Sigma*(1385
