RHIC上极化质子-质子碰撞中的$χ_{cJ}$极化

$χ_{cJ}$ Polarization in Polarized Proton-Proton Collisions at RHIC

Gouranga C. Nayak

摘要:

利用非相对论QCD(NRQCD)色八重态机制,研究了RHIC质子-质子碰撞中$\sqrt{s}$ = 200 GeV和500 GeV的具有确定极化的$χ_{cJ}$的包容产生.本文给出了PHENIX探测器接收范围内RHIC极化p-p碰撞中特定极化下产生的$χ_{c0}$、$χ_{c1}$和$χ_{c2}$的快度分布。我们还提出了相应的结果的自旋不对称性。

英文摘要:

We study inclusive $χ_{cJ}$ production with definite polarizations in polarized proton-proton collisions at $\sqrt{s}$ = 200 GeV and 500 GeV at RHIC by using non-relativistic QCD (NRQCD) color-octet mechanism. We present results of rapidity distribution of $χ_{c0}$, $χ_{c1}$ and $χ_{c2}$ production with specific polarizations in polarized p-p collisions at RHIC within the PHENIX detector acceptance range. We also present the corresponding results for the spin asymmetries.
