在LHC上带电强子R_AA随p_T的变化

Charged hadron R_AA as a function of p_T at the LHC

Thorsten Renk, Kari J. Eskola

摘要:

利用流体动力学演化描述软介质引起的能量损失,计算了辐射能量损失图中带电强子的核抑制因子R_AA。一个微喷+饱和图像提供了LHC能量的初始条件和首阶微扰QCD(LO pQCD)被用来计算部分子谱之前的能量损失的失真。

英文摘要:

We compute the nuclear suppression factor R_AA for charged hadrons within a radiative energy loss picture using a hydrodynamical evolution to describe the soft medium inducing energy loss. A minijet + saturation picture provides initial conditions for LHC energies and leading order perturbative QCD (LO pQCD) is used to compute the parton spectrum before distortion by energy loss.
