The analysis of the latest most accurate experimental data on neutron decay for the possibility of the existence of the right vector boson <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"> <a:mrow> <a:msub> <a:mi>W</a:mi> <a:mi>R</a:mi> </a:msub> </a:mrow> </a:math> 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 <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" display="inline"> <c:mrow> <c:msub> <c:mi>W</c:mi> <c:mi>R</c:mi> </c:msub> </c:mrow> </c:math> with a mass of <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" display="inline"> <e:mrow> <e:msub> <e:mi>M</e:mi> <e:mrow> <e:msub> <e:mi>W</e:mi> <e:mi>R</e:mi> </e:msub> </e:mrow> </e:msub> <e:mo>=</e:mo> <e:msubsup> <e:mn>304</e:mn> <e:mrow> <e:mo>−</e:mo> <e:mn>20</e:mn> </e:mrow> <e:mrow> <e:mo>+</e:mo> <e:mn>24</e:mn> </e:mrow> </e:msubsup> <e:mtext> </e:mtext> <e:mtext> </e:mtext> <e:mi>GeV</e:mi> </e:mrow> </e:math> , and a mixing angle with <g:math xmlns:g="http://www.w3.org/1998/Math/MathML" display="inline"> <g:mrow> <g:msub> <g:mi>W</g:mi> <g:mi>L</g:mi> </g:msub> </g:mrow> </g:math> : <i:math xmlns:i="http://www.w3.org/1998/Math/MathML" display="inline"> <i:mrow> <i:mi>ζ</i:mi> <i:mo>=</i:mo> <i:mo>−</i:mo> <i:mn>0.039</i:mn> <i:mo>±</i:mo> <i:mn>0.0</i:mn> <i:mn>1</i:mn> <i:mn>4</i:mn> </i:mrow> </i:math> . 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 <k:math xmlns:k="http://www.w3.org/1998/Math/MathML" display="inline"> <k:mrow> <k:mi>C</k:mi> <k:mi>P</k:mi> </k:mrow> </k:math> violation in decays of neutral <m:math xmlns:m="http://www.w3.org/1998/Math/MathML" display="inline"> <m:mi>K</m:mi> </m:math> -mesons and <o:math xmlns:o="http://www.w3.org/1998/Math/MathML" display="inline"> <o:mi>D</o:mi> </o:math> -mesons 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 <q:math xmlns:q="http://www.w3.org/1998/Math/MathML" display="inline"> <q:mrow> <q:mi>C</q:mi> <q:mi>P</q:mi> </q:mrow> </q:math> violation.
