$K*(892)^0$ production in p+p interactions at 158 GeV/c from NA61/SHINE

The measurement of $K^{*}(892)^0$ resonance production via its $K^{+}\pi^{-}$ decay mode in inelastic p+p collisions at beam momentum 158 GeV/c ($\sqrt{s_{NN}}=17.3$ GeV) is presented.

Sumario:The measurement of $K^{*}(892)^0$ resonance production via its $K^{+}\pi^{-}$ decay mode in inelastic p+p collisions at beam momentum 158 GeV/c ($\sqrt{s_{NN}}=17.3$ GeV) is presented. The data were recorded by the NA61/SHINE hadron spectrometer at the CERN Super Proton Synchrotron. The first ever double differential measurements and $p_T$-integrated spectra of $K^{*}(892)^0$ at beam momenta of 158 GeV/c was done by using the template fitting method. The full phase-space yields, mass and width of $K^{*}(892)^0$ mesons are compared with Hadron Resonance Gas models as well as with world data on p+p and nucleus-nucleus collisions.
