论文摘要
恒星处的每个触发器的半含量带电光谱由事件活动（EA）列出，该事件活动（EA）由光束梁计数器（BBC）信号在Au-to-to-theende方向上确定。所选的EA确定是由时间投影室（TPC）（$ |η| <1 $）与EA（$η_\ Mathrm {ea} \ in [-5，2] $）之间的相关性激励。相对于低EA处的光谱，在高EA处的每个触发器的喷射光谱被抑制。毕达氏菌的调查驳斥了抑制作用是由于射流运动学与EA和TPC的接受之间的微不足道自相关引起的。
Semi-inclusive charged jet spectra per trigger at STAR are presented binned by event activity (EA) as determined by the Beam Beam Counter (BBC) signal in the Au-going direction. The selected EA determination is motivated by correlations between the number of charged tracks in the Time Projection Chamber (TPC) ($|η|<1$) and EA ($η_\mathrm{EA}\in[-5,-2]$) which are also presented. The jet spectra per trigger at high EA are suppressed relative to the spectra at low EA. A PYTHIA investigation refutes that the suppression results from a trivial autocorrelation between jet kinematics and the acceptance of the EA and the TPC.
