Abstract

One of the primary goals of the STAR spin program at RHIC is the measurement of the double longitudinal asymmetry ALL in inclusive jet production. This measurement will allow STAR to determine the polarized gluon distribution function DeltaG in the Bjorken x region of 0.03<x<0.3. Inclusive jet production is a theoretically desirable way to measure DeltaG, as it is independent of fragmentation functions. This contribution presents STAR's preliminary 2005 measurements of ALL for inclusive jet production extracted from 3.1 pb−1 of data at [square root of]s=200 GeV and 50% beam polarization. The asymmetry is calculated over the transverse momentum region 5 < pT < 30 GeV/c and compared with theoretical predictions incorporating several gluon polarization scenarios. Systematic uncertainties from false asymmetries, jet reconstruction, and triggering are discussed. At the present level of statistics, the measured asymmetry disfavors maximal gluon polarization but cannot yet distinguish between other theoretical scenarios.
