Transverse Spin Studies with STAR at RHIC
arXiv:hep-ex/0607003 · doi:10.1142/9789812706706_0163
Abstract
STAR has observed sizable transverse single-spin asymmetries for inclusive pi^0 production at forward rapidity in p+p collisions at sqrt{s}=200 GeV. These asymmetries may arise from either the Sivers or Collins effect. Studies are underway during the current RHIC run to elucidate the dynamics that underlie these single-spin asymmetries. Additional measurements are underway to search for the Sivers effect in mid-rapidity di-jet production.
