Title: Longitudinal double-spin asymmetry and cross section for inclusive jet production in polarized proton collisions at {radical}{ovr s} = 200 GeV.

Abstract

We report a measurement of the longitudinal double-spin asymmetry A{sub LL} and the differential cross section for inclusive midrapidity jet production in polarized proton collisions at {radical}s = 200 GeV. The cross section data cover transverse momenta 5 < p{sub T} < 50 GeV/c and agree with next-to-leading order perturbative QCD evaluations. The A{sub LL} data cover 5 < p{sub T} < 17 GeV/c and disfavor at 98% C.L. maximal positive gluon polarization in the polarized nucleon.
