摘要:

在LHC上用CMS探测器研究了核子-核子质心能量为2.76TeV的Pb-Pb碰撞中的双喷流。结果表明,在Pb-Pb碰撞中,无论是前导喷流还是次前导喷流,喷流碎裂成横向动量pT > 4GeV/c的带电粒子径迹的碎裂函数与pp碰撞中的类似。此外,对2011年获得的高统计PbPb数据的研究表明,淬火现象存在于超过300 GeV/c的最高喷流pT值。

英文摘要:

Dijets in PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76 TeV are studied with the CMS detector at the LHC. It is shown that the fragmentation functions of jets into charged particle tracks with transverse momenta pT > 4 GeV/c in PbPb collisions are similar to those in pp collisions, for both the leading and subleading jets. In addition, study of high statistics PbPb data acquired in 2011 shows that the quenching phenomenon exists up to highest jet pT values in excess of 300 GeV/c.
