Multinucleon ejection model for Meson Exchange Current neutrino interactions
A model is proposed to describe pairs or triples of nucleons ejected from
nucleus as a result of Meson Exchange Current neutrino interaction. The model
can be easily implemented in Monte Carlo neutrino event generators. It can
provide a help in identifying true charge current quasielastic events and allow
for better determination of the systematic error of neutrino energy
reconstruction in neutrino oscillation experimentsComment: A version published in PRC, with several improvements wrt the

Operator Formalism for Bosonic Beta-Gamma Fields on General Algebraic Curves
An operator formalism for bosonic systems on arbitrary
algebraic curves is introduced. The classical degrees of freedom are identified
and their commutation relations are postulated. The explicit realization of the
algebra formed by the fields is given in a Hilbert space equipped with a
bilinear form. The construction is based on the "gaussian" representation for
systems on the complex sphere [Alvarez-Gaum\' e et al, Nucl.
Phys. B 311 (1988) 333]. Detailed computations are provided for the two and
four points correlation functions.Comment: 26 pages, plain TeX + harvma
Neutrino energy reconstruction from one muon and one proton events
We propose a new method of selection of high purity charge current
quasielastic neutrino events with a good reconstruction of interacting neutrino
energy. Performance of the method was verified with several tests using GENIE,
NEUT and NuWro Monte Carlo events generators with carbon and argon targets. The
method can be useful in neutrino oscillation studies with a few GeV energy
beams.Comment: 8 pages, 5 figure
