Özet

A first measurement of the production of K*(892)± vector mesons, observed through the decay chain K*(892)± → K0Sπplusmn;, in neutral current deep-inelastic ep scattering with the H1 detector is presented [1]. The analysis is based on data taken on the 2005-2007 data taken with the total integrated luminosity of 302 pb-1. Inclusive cross sections are presented as a function of the various kinematic variables. The phase space of the measurement is restricted to 5 < Q2 < 100 GeV-1, 0.1 < y < 0.6, -1.5 < η(K*±) < 1.5 and pT (K*±) > 1 GeV. The results are compared to predictions of leading order Monte Carlo models with parton showers.
