Abstract | First measurements of K*(892) vector mesons, observed through the
decay chain K*+- --> K0s pi+-, in neutral current deep-inelastic ep
scattering with the H1 detector are presented. The analysis is based
on data taken in the HERA-II running period. Inclusive cross sections
are presented as a function of the transverse momentum squared P_T*^2,
the rapidity y* and the centre-of-mass energy W of the hadronic final
state. The phase space of the events is restricted to 4 < Q2 < 100 GeV2,
0.1 < y < 0.6 and -1.5 < eta(K*) < 1.5. The results are compared to
predictions of leading order Monte Carlo models matched with parton
showers. |
