  Due to the assumption that sterile neutrinos are right-handed neutrinos, an
analysis of the modern experimental situation in neutron decay for right-handed
currents was carried out. As a result of the analysis, it was found that there
are indications of the existence of a right-handed vector boson $W_R$ with a
mass $M_{W_R}\approx 870_{-140}^{+260} \text{GeV}$ and a mixing angle with
$W_L$: $\zeta=0.061_{-0.024}^{+0.017}$. This circumstance is the basis for
discussing the possibility of expanding the Standard Model with an additional
gauge vector boson $W_R$ and right-handed neutrinos.
