About estimations of an one-photon background in neutrino oscillation experiments at low neutrino energies
V. P. Efrosinin
The possible sources of one-photon radiation as background for quasi-elastic reaction nu_mu+n to mu^-+p are considered. The ones are relevant in experiments on determination of osc…

About the quark currents in leptonic decaies of pseudoscalar mesons
V. P. Efrosinin, A. N. Khotyantsev
With usage of obvious mechanisms of quark currents the amplitudes of leptonic decaies of pseudoscalar mesons are investigated. The estimation for a constant of leptonic decay of th…

Form factors of the Kmu3 decay in the spectator approximation of the Standard Model
V. P. Efrosinin, A. N. Khotyantsev
We have calculated the parameter Ksi(0)=f-(0)/f+(0) of the Kmu3 decay in the spectator approximation of the Standard Model. It was obtained that Ksi(0) ~ -0.02.
