The NP right-chiral $CC$ coupling constant estimation in neutrino oscillation experiments

Abstract

The error probability of the discrimination of the Standard Model (SM) with massive neutrinos and its new physics (NP) model extension in experiments of the muon neutrino oscillation, following the pion decay ${\pi }^{+}\to {\mu }^{+}+{\nu }_{\mu }$, is calculated. The stability of the estimation of the NP charged current coupling constant ${\epsilon }_R$ is analysed and the robustness of this estimation is checked. It is shown that the upper bound on the error probability of erroneous identification of the Standard Model with its NP model extension has reached the significantly small value of approximately $2.3\times 10^{-6}$.
