What are the Neutrino Masses
The possible source of the production of neutrino with large masses is considered. For this purpose the reaction nu+n to e+p+gamma, in which the electron in neW+ vertex is produced off-mass-shell, is studied.

About estimations of an one-photon background in neutrino oscillation experiments at low neutrino energies
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 oscillation parameters at low neutrino energies (E_nu^lab~1 GeV). The estimation for the cross section of reaction nu_mu+n to mu^-+p+gamma is given at E_nu^lab=0.7 GeV as 0.65% from the corresponding cross section of quasi-elastic reaction.

About the quark currents in leptonic decaies of pseudoscalar mesons
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 the D+ meson is obtained, f_D+ ~ 0.23 GeV.

Form factors of the Kmu3 decay in the spectator approximation of the Standard Model
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.

Transverse Muon Polarization in $K^{\pm}\toπ^0μ^{\pm}ν$ Decay Induced by the Two-Photon Final-State Interaction
We calculate the transverse muon polarization in the decay $K^{\pm}\toπ^0μ^{\pm}ν$ induced by the electromagnetic two-photon final-state interaction. For the central part of the Dalitz plot the typical value of this polarization is about $4\times 10^{-6}$.
