sqrt(snn)= 2.76 TeV与ALICE碰撞中的带电粒子多重数和横向能量

Charged-particle multiplicity and transverse energy in Pb-Pb collisions at sqrt(snn) = 2.76 TeV with ALICE

Constantin Loizides

摘要:

测量了sqrt(sNN)= 2.76TeV的Pb-Pb碰撞中快度带电粒子多重数和横向能量随中心度的变化.使用Glauber模型估计由ALICE检测器记录的非弹性截面的分数。参与核子的数量缩放的结果进行比较与PP碰撞在相同的碰撞能量,在显着较低的能量,并与模型的基础上不同的机制,在核碰撞中的粒子生产类似的结果。

英文摘要:

The measurements of charged-particle multiplicity and transverse energy at mid-rapidity in Pb-Pb collisions at sqrt(sNN) = 2.76 TeV are reported as a function of centrality. The fraction of the inelastic cross section recorded by the ALICE detector is estimated using a Glauber model. The results scaled by the number of participating nucleons are compared with pp collisions at the same collision energy, to similar results obtained at significantly lower energies, and with models based on different mechanisms for particle production in nuclear collisions.
