论文摘要
提出了GSI的Hades实验收集的1.23A GEV的光束能量中质子的定向流量的中心性依赖性。相对于使用前壁霍迪镜估计的平面进行测量。评估由于非流量相关性和相关检测器效应而引起的偏差。使用来自前向壁通道和使用Hades跟踪系统重建的质子组构成的各种前向速度区域的观众平面的估计来量化相应的系统不确定性。
Centrality dependence of the directed flow of protons in Au+Au collisions at the beam energy of 1.23A GeV collected by the HADES experiment at GSI is presented. Measurements are performed with respect to the spectators plane estimated using the Forward Wall hodoscope. Biases due to non-flow correlations and correlated detector effects are evaluated. The corresponding systematic uncertainties are quantified using estimates of the spectators plane from various forward rapidity regions constructed from groups of Forward Wall channels and protons reconstructed with the HADES tracking system.
