STAR实验中$\sqrt{\rm s}$ = 200 GeV pp碰撞产生$J/ψ$

$J/ψ$ production in pp collisions at $\sqrt{\rm s}$=200GeV in the STAR experiment

Mauro R. Cosentino

摘要:

在这项工作中,我们提出的$J/ψ$测量p+p碰撞的STAR合作夸克偶素计划。该测量旨在成为更全面系统地研究夸克偶素态产生的基线测量,以了解它们在介质中的变化。在这里,我们报告的总截面和$p_T$分布,并发现它们是一致的pQCD CEM预测,以及以前的测量在相同的质心能量。

英文摘要:

In this work we present the $J/ψ$ measurement in p+p collisions within the STAR collaboration Quarkonium program. This measurements aim to be the baseline measurement of a more comprehensive systematic study of quarkonium states production in order to understand their in medium modification. Here we report the total cross section and $p_T$ distribution, and find them to be consistent with pQCD CEM predictions as well as to previous measurements at the same center-of-mass energy.
