摘要：
Preliminary results are presented for single-spin charged particle asymmetries in PP collisions detected with the STAR beam-beam counters at pseudorapidity n approximate to 4. A nonzero analyzing power is observed; the magnitude is approximately half of that seen for the RHIC Coulomb-nuclear interference polarimeters. Single- and double-spin asymmetry measurements for leading charged particles detected with the STAR time projection chamber are also described. The preliminary results are consistent with zero.
