sqrt(s_NN)= 200 GeV Au+Au碰撞中的高p_T识别强子比

High p_T identified hadron ratios in sqrt(s_NN)=200GeV Au+Au Collisions

T. Sakaguchi

摘要:

RHIC的PHENIX探测器在sqrt(s_NN)= 200 GeV的Au+Au碰撞中测量到了高的p_T可识别强子比。在目前的系统误差和统计误差范围内,在3.8GeV/c以下测得的pbar/p比几乎与p_T和中心性无关。重子介子比是通过p/pi和pbar/pi比测量的,直到3.8GeV/c,表明它们是强烈依赖于中心性的。

英文摘要:

The PHENIX detector at RHIC measured high p_T identified hadron ratios in sqrt(s_NN) = 200GeV Au+Au collisions. Within the current systematic and statistical errors, pbar/p ratios that are measured up to 3.8GeV/c are almost independent of both p_T and centrality. The baryon to meson ratio is measured through p/pi and pbar/pi ratios up to 3.8GeV/c, showing they are strongly centrality dependent.
