RHIC极化pp碰撞中喷流的产生

Jet Production in Polarized pp Collisions at RHIC

C. A. Gagliardi

摘要:

STAR合作测量了在sqrt{s} = 200 GeV的极化p+p碰撞中包容性喷流产生的纵向双自旋不对称性。这些结果对核子内的胶子极化设置了重要的新约束。未来对双喷流产生的不对称性的测量将为胶子极化的动量依赖性Δ g(x,Q^2)提供直接的途径。

英文摘要:

The STAR Collaboration has measured the longitudinal double-spin asymmetry for inclusive jet production in polarized p+p collisions at sqrt{s} = 200 GeV. The results set significant new constraints on the gluon polarization within the nucleon. Future measurements of asymmetries for di-jet production will provide direct access to the momentum dependence of the gluon polarization, Delta g(x,Q^2).
