Abstract

We report STAR measurements of the longitudinal double-spin asymmetry A[subscript LL], the transverse single-spin asymmetry A[subscript N], and the transverse double-spin asymmetries A[subscript Σ] and [subscript ATT] for inclusive jet production at mid-rapidity in polarized p+p collisions at a center-of-mass energy of √s=200 GeV. The data represent integrated luminosities of 7.6 pb[superscript -1] with longitudinal polarization and 1.8 pb[superscript -1] with transverse polarization, with 50%–55% beam polarization, and were recorded in 2005 and 2006. No evidence is found for the existence of statistically significant jet A[subscript N], A[subscript Σ], or A[subscript TT] at mid-rapidity. Recent model calculations indicate the AN results may provide new limits on the gluon Sivers distribution in the proton. The asymmetry A[subscript LL] significantly improves the knowledge of gluon polarization in the nucleon.
