Revisiting and 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 , ,
and nuclear targets in 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 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 Mesons off the Nucleon
The strange particle production induced by (anti)neutrino off nucleon has
been studied for and 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 , 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
(1385) resonance and for eta production (1535) and
(1650) resonances are included.Comment: To appear in AIP Conf. Proc. of the Workshop CETUP*14, 12 Pages, 13

Antineutrino induced antikaon production off the nucleon
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. This version matches accepted version for

spectrum of acquired demyelinating disorders of the central nervous system in adults in a tertiary care hospital
Acquired demyelinating disorders of the central nervous system are diverse group of conditions characterized by destruction or disturbance of myelin sheath in the central nervous system i.e. brain and spinal cord. These vary in their causes, clinical presentations, and prognosis
