用ALICE实验测量LHC的J/psi产量

Measurement of J/psi production at the LHC with the ALICE experiment

M. Gagliardi

摘要:

ALICE(大型离子对撞机实验)旨在研究高能量密度下核物质的行为以及向夸克-胶子等离子体(QGP)的过渡,预计将在超相对论性重离子碰撞中发生。在ALICE物理计划中,Pb-Pb和pp碰撞中的夸克偶素产生测量起着至关重要的作用。在ALICE中,夸克偶素的探测在正向(在双μ子通道中)和中快度(在双电子通道中)都是可能的。2010年,大型强子对撞机提供了sqrt(s)=7 TeV的pp碰撞和sqrt(sNN)=2.76 TeV的Pb-Pb碰撞。ALICE的结果J/psi的生产PP碰撞,随着铅铅分析的状态。

英文摘要:

ALICE (A Large Ion Collider Experiment) aims at studying the behaviour of nuclear matter at high energy densities and the transition to the Quark Gluon Plasma (QGP), expected to occur in ultra-relativistic heavy ion collisions. Quarkonia production measurements in both Pb-Pb and pp collisions play a crucial role in the ALICE physics program. Quarkonium detection is possible in ALICE at both forward (in the dimuon channel) and mid-rapidity (in the dielectron channel). In 2010, the Large Hadron Collider has provided pp collisions at sqrt(s)=7 TeV and Pb-Pb collisions at sqrt(sNN)=2.76 TeV. The ALICE results on J/psi production in pp collisions are presented, along with the status of the Pb-Pb analysis.
