Double Longitudinal Spin Asymmetry in Inclusive Jet Production in Polarized P+p Collisions at √ S = 200 Gev
نویسنده
چکیده
We present preliminary measurements of the cross section and the double longitudinal spin asymmetry in inclusive jet production in polarized p+p collisions at √ s = 200 GeV. The measured cross section agrees well with NLO pQCD calculations over seven orders of magnitude. The observed spin asymmetries are consistent with theoretical evaluations based on deeply inelastic scattering data and tend to disfavor a large positive gluon polarization.

متن کاملConstraints on ∆G through Longitudinal Double Spin Asymmetry Measurements of Inclusive Jet Production in Polarized p+p Collisions at 200 GeV
We report measurements of the longitudinal double spin asymmetry for inclusive jet production using polarized p+p collisions at √ s = 200 GeV at RHIC. Results from the 2005 and 2006 runs are presented. These results set substantial new constraints on the polarized gluon distribution in the proton over the kinematic range 0.02 < x < 0.3, when compared to next-to-leading order global analyses of ...

متن کاملLongitudinal Spin Asymmetry and Cross Section of Inclusive π0 Production in Polarized p+ p Collisions at RHIC
We present the first measurement of the cross section and the double longitudinal spin asymmetry of inclusive π0 production in polarized p+p collisions at √ s = 200 GeV at mid-rapidity with the STAR detector, using the barrel electromagnetic calorimeter. The measured cross section is compared to NLO pQCD calculations and can provide constraints on the pion fragmentation functions. Fragmentation...
