在RHIC的STAR实验中对200次GeV p+p和d+Au碰撞中喷流的研究

Jet studies in 200 GeV p+p and d+Au collisions from the STAR experiment at RHIC

Jan Kapitan

摘要:

近年来在RHIC重离子碰撞中的全喷注重建研究取得了新进展,使其成为定量研究高能量密度QCD的有力工具。d+Au碰撞中的测量对于从介质引起的kT展宽和喷注猝灭中分离出初态核效应是非常重要的。此外,与p+p中的测量值进行比较,可以获得冷核物质效应。给出了2007-2008年RHIC实验中200 GeV p+p和d+Au碰撞的包含喷注pT谱和双喷注关联(kT)。

英文摘要:

Recent progress in full jet reconstruction in heavy-ion collisions at RHIC makes it a promising tool for the quantitative study of the QCD at high energy density. Measurements in d+Au collisions are important to disentangle initial state nuclear effects from medium-induced k_T broadening and jet quenching. Furthermore, comparison to measurements in p+p gives access to cold nuclear matter effects. Inclusive jet p_T spectra and di-jet correlations (k_T) in 200 GeV p+p and d+Au collisions from the 2007-2008 RHIC run are presented.
