PDMATHAAB = 200时p+p和d+Au碰撞中J/ $ψ$的产生

J/$ψ$ Production in p+p and d+Au Collisions at $\sqrt{S_{NN}}$ = 200 GeV at STAR

Chris Perkins

摘要:

我们目前的分析J/ $ψ$生产范围$-1.0 < η< 4.2$在p+p和d+Au碰撞使用双电子数据在2008年运行期间与星实验在布鲁克海文国家实验室。STAR独特的前向能力,特别是前向介子谱仪电磁量能器,使我们有可能使用高$x_F$前向粒子在不对称部分子碰撞中产生的质子波函数的内在魅力组件进行调查。d+Au碰撞中的中快度测量扩展了我们对重夸克偶素产生及其通过冷核物质输运的机制的理解。

英文摘要:

We present analysis of J/$ψ$ production over the range $-1.0 < η< 4.2$ in p+p and d+Au collisions using di-electron data taken during the 2008 run with the STAR experiment at Brookhaven National Laboratory. STAR's unique forward capabilities, especially the Forward Meson Spectrometer electromagnetic calorimeter, allow us the possibility of investigating the intrinsic charm components of the proton wave function using high-$x_F$ forward particles produced in asymmetric partonic collisions. Mid-rapidity measurements in d+Au collisions extend our understanding of the mechanisms underlying heavy quarkonium production and its transport through cold nuclear matter.
