Production properties of K*(892)^± ; ; vector mesons and their spin alignment as measured in the NOMAD experiment
First measurements of K*(892)± ; ; mesons production properties and their spin alignment in ν µ ; ; charged current (CC) and neutral current (NC) interactions are presented. The analysis of the full data sample of the NOMAD experiment is performed in di.erent kinematic regions. For K*+ and K*-mesons produced in nu-mu CC interactions and decaying into K^0 pi^± ; ; we have found the following yields per event: (2.6± ; ; 0.2 (stat.)± ; ; 0.2 (syst.))% and (1.6± ; ; 0.1 (stat.)± ; ; 0.1 (syst.))% respectively, while for the K*+ and K*- mesons produced in nu NC interactions the corresponding yields per event are: (2.5± ; ; 0.3 (stat.)± ; ; 0.3 (syst.))% and (1.0± ; ; ; ; 0.3 (stat.)± ; ; ; ; 0.2 (syst.))%. The results obtained for the rho_00 parameter, 0.40± ; ; 0.06 (stat.)± ; ; 0.03 (syst.) and 0.28± ; ; 0.07 (stat.)± ; ; 0.03 (syst.) for K*(892)^+ and K*(892)^- produced in nu-mu CC interactions, are compared to theoretical predictions tuned on LEP measurements in e^+e^- annihilation at the Z^0 pole. For K*(892)^+ mesons produced in nu NC interactions the measured rho_00 parameter is 0.66± ; ; 0.10 (stat.)± ; ; 0.05 (syst.).
