Using jet asymmetries to access ?G at STAR

Using jet asymmetries to access ?G at STAR

Producción científica: Paper › revisión exhaustiva

Resumen

We present the first inclusive jet longitudinal double spin asymmetry A_LLand differential cross-section measurement from STAR. This analysis reflects 1 pb^-1of polarized p¯p¯ data taken at vs = 200 GeV with beam polarizations of 30-45% in years 2003 and 2004. Agreement between the measured differential cross-section and next-to-leading order (NLO) calculations validate the interpretation of the asymmetry results within the framework of perturbative Quantum Chromodynamics (pQCD). A_LLis compared to NLO pQCD calculations, which incorporate several possible gluon helicity distributions, and is shown to disfavor the maximum gluon scenario.
