Spin Alignment of $K^*(892)^±$ Vector Mesons and $\Lambda^{0}$, $\bar\Lambda^{0}$ Polarization in $\nu_{\mu}$ CC and NC Interactions in the NOMAD Experiment

This analysis represents the results of the measurements of the spin alignment of the K*$(892)^{±}$ mesons in $v_{µ}$. charged current and neutral current interactions. The analysis of the full data sample of the NOMAD experiment allowed to perform these measurements in different kinematic regions....

Sumario:This analysis represents the results of the measurements of the spin alignment of the K*$(892)^{±}$ mesons in $v_{µ}$. charged current and neutral current interactions. The analysis of the full data sample of the NOMAD experiment allowed to perform these measurements in different kinematic regions. Obtained results a.re compared with the theoretical predictions based on the results of the LEP experiments in $e^{+}$ $e^{-}$ annihilation at the $Z^{0}$ pole. First results on the measurements of the $\Lambda^{0}$ and $\bar\Lambda^{0}$ polarization in neutral current interaction are presented.
