K∗(892) meson production in inelastic p+p interactions at 158 GeV/c beam momentum measured by NA61/SHINEat the CERN SPS

The measurement of K∗(892)0 resonance production via its K+π− decay mode in inelastic p+p collisions at beam momentum 158 Ge V /c (sNN−−−−√=17.3 Ge 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 ext...

Zusammenfassung:The measurement of K∗(892)0 resonance production via its K+π− decay mode in inelastic p+p collisions at beam momentum 158 Ge V /c (sNN−−−−√=17.3 Ge 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±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.
