Jet Production in Polarized pp Collisions at RHIC
暂无分享,去创建一个
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).
