Abstract
The measurement of K^{*}(892)^0 resonance production via its K^{+}pi ^{-} decay mode in inelastic p+p collisions at beam momentum 158 text{ Ge }text{ V }!/!c (sqrt{s_{NN}}=17.3 text{ Ge }text{ V }) is presented. The data were recorded by the NA61/SHINE hadron spectrometer at the CERN Super Proton Synchrotron. The template method was used to extract the K^{*}(892)^0 signal and double-differential transverse momentum and rapidity spectra were obtained. The full phase-space mean multiplicity of K^{*}(892)^0 mesons was found to be (78.44 pm 0.38 mathrm {(stat)} pm 6.0 mathrm {(sys)) cdot 10^{-3}}. The NA61/SHINEresults are compared with the Epos1.99 and Hadron Resonance Gas models as well as with world data from p+p and nucleus–nucleus collisions.
