论文摘要
我们研究了$ \ sqrt {s_ {nn}} = $ 7.7-200 gev的au + au碰撞的浅叶载体的定向流。初始条件取自合适的Glauber模型，该模型在相对论流体动力学的框架内进化。在适当校准初始条件之后，将识别出的光味的载体的速度 - odd定向流量（$ v_1 $）的模型计算进行了比较，以描述带电粒子多重性和净值的速度依赖性。为了合理地选择初始条件，我们能够描述已确定的强子$ v_ {1} $的测得的速度和梁的能量依赖性，包括观察到的$ v_1 $在巴里子和反巴里子之间分裂。
We have studied the directed flow of light-flavor hadrons for Au + Au collisions at $\sqrt{S_{NN}}=$ 7.7 - 200 GeV. The initial condition is taken from a suitable Glauber model which is further evolved within the framework of relativistic hydrodynamics. Model calculations of the rapidity-odd directed flow ($v_1$) of identified light-flavor hadrons are compared with the available experimental data after suitably calibrating the initial condition to describe the rapidity dependence of charged particle multiplicity and net-proton yield. For reasonable choice of the initial condition, we are able to describe the measured rapidity and beam energy dependence of identified hadron $v_{1}$ including the observed $v_1$ splitting between baryons and anti-baryons.
