| contents | The analysis of the latest most accurate experimental data on neutron decay for the possibility of the existence of the right vector boson $W_R$ is carried out. As a result of the analysis within the framework of the left-right symmetric model, it was found that there is an indication of the existence of the right vector boson $W_R$ with a mass of $M_{W_R}=304_{-20}^{+24} \text{GeV}$, and a mixing angle with $W_L: ζ= -0.039\pm 0.014$. It is shown that this result does not contradict the experiments at colliders to search for a hypothetical vector boson. In addition, it is shown that it is possible to describe the effects of CP violation in decays of neutral $K$-mesons, $D$-mesons and $B_s^0$ using the parameters of the extended left-right symmetric model obtained from neutron decay, i.e. squared masses of the left and right bosons ratio and the mixing angle. The formation of baryon-lepton asymmetry of the Universe is considered within the framework of the left-right model of weak interaction with CP violation. A new experimental design for measuring neutron decay asymmetries with increased accuracy is presented. |
