MEASUREMENT OF THE DOUBLE LONGITUDINAL SPIN ASYMMETRY IN INCLUSIVE JET PRODUCTION IN POLARIZED P+P COLLISIONS AT S**(1/2) = 200 GEV.

PDF Version Also Available for Download.

Description

We present preliminary results for the first measurements of the double longitudinal spin asymmetry A{sub LL} in inclusive jet production at mid-rapidity in polarized proton-proton collisions at {radical}s = 200 GeV. The data amount to {approx} 0.5 pb{sup -1} collected at RHIC in 2003 and 2004 with beam polarizations up to 45%. The jet transverse energies are in the range of 5 < p{sub T} < 17 GeV/c. The data are consistent with theoretical evaluations using deep-inelastic scattering parametrizations for gluon polarization in the nucleon, and tend to disfavor large positive values of gluon polarization.
