Extracting the Gluon Piece of the Spin Puzzle
New Inclusive Evidence Jet Results from STAR
Renee Fatemi, University of Kentucky
Unraveling the nucleon spin puzzle has been the focus of experimental and theoretical efforts since polarized deep-inelastic scattering (DIS) experiments found that the quark contribution to the nucleon spin is small. Subsequently,measurements sensitive to the gluon contribution (ΔG) to the total spin of the nucleon have been widely pursued and is a flagship effort within the STAR Spin program. This talk will focus on results from the mid-rapidity inclusive jet channel at = 200 GeV, and the substantial new constraints placed on ∆G when compared to those from a next-to-leading order analysis of DIS data. Future STAR plans for continued progress on ΔG measurements will be discussed.
