Abstract
The analysis of the latest most accurate experimental data on neutron decay for the possibility of the existence of the right-handed vector boson \({{W}_{{\text{R}}}}\) is carried out. As a result of the analysis, it is found that there is an indication of the existence of the right-handed vector boson \({{W}_{{\text{R}}}}\) with a mass of \({{M}_{{{{W}_{{\text{R}}}}}}} \approx 319_{{ - 20}}^{{ + 26}}\) GeV and a mixing angle with \({{W}_{{\text{L}}}}\) : ζ = –0.034 ± 0.013. This result should be considered, on the one hand, as a challenge to experimental physics at colliders, where the upper limit on the mass of the right-handed vector boson \({{W}_{{\text{R}}}}\) is significantly higher and, on the other hand, as evidence that even more accurate measurements of neutron decay and its theoretical analysis are needed.
