Popis: Abstract The measurement of $$K^{*}(892)^0$$ K∗(892)0 resonance production via its $$K^{+}\pi ^{-}$$ K+π- decay mode in inelastic p+p collisions at beam momentum 158 $$\text{ Ge }\text{ V }\!/\!c$$ GeV/c ($$\sqrt{s_{NN}}=17.3$$ sNN=17.3 $$\text{ Ge }\text{ V }$$ GeV ) 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 $$K^{*}(892)^0$$ K∗(892)0 signal and double-differential transverse momentum and rapidity spectra were obtained. The full phase-space mean multiplicity of $$K^{*}(892)^0$$ K∗(892)0 mesons was found to be $$(78.44 \pm 0.38 \mathrm {(stat)} \pm 6.0 \mathrm {(sys)) \cdot 10^{-3}}$$ (78.44±0.38(stat)±6.0(sys))·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.
