论文摘要
$ k^{*}(892)^0 $共振的测量通过其$ k^{+}π^{ - } $ decay模式在Beam Momentum 158 Gev/$ c $($ \ \ \ sqrt {s_ {nn}} = 17.3 $ GEV上的弹性P+P碰撞中,请列出。数据由CERN超级质子同步器处的Na61/Shine Hadron光谱仪记录。 \ textit {template}方法用于提取$ k^{*}(892)^0 $信号和双差分横向动量和速度光谱。 $ k^{*}(892)^0 $ MESON的完整空间平均多数性被发现为$(78.44 \ pm 0.38 \ pm Mathrm {(stat)} \ pm 6.0 \ pm 6.0 \ mathrm {(sys))\ cdot 10^{ - 3}} $。将Na61/光泽结果与EPOS1.99和强子共振气体模型以及P+P和Nucleus-Nucleus碰撞的世界数据进行了比较。
The measurement of $K^{*}(892)^0$ resonance production via its $K^{+}π^{-}$ 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 \textit{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/SHINE results are compared with the EPOS1.99 and Hadron Resonance Gas models as well as with world data from p+p and nucleus-nucleus collisions.
