Constraint on Δg(x) from π^0 production at RHIC
M. Hirai, S. Kumano, N. Saito
We determine the polarized gluon distribution Δg(x) by a global analysis using current DIS and π^0 asymmetry data. The π^0 data from RHIC-Spin experiments provide a strong constrai…
Single Transverse-Spin Asymmetry in Very Forward and Very Backward Neutral Particle Production for Polarized Proton Collisions at sqrt{s} = 200 GeV
Y. Fukao, M. Togawa, A. Bazilevsky +24
In the 2001-2002 running period of the Relativistic Heavy Ion Collider (RHIC), transversely polarized protons were accelerated to 100 GeV for the first time, with collisions at sqr…
Constraint on at large
M. Hirai, S. Kumano, N. Saito
We investigate the polarized gluon distribution Δg(x) by a global analysis of current DIS data and the π^0 data from RHIC-Spin experiments. The π^0 data provide a strong constraint…
Determination of polarized parton distribution functions with recent data on polarization asymmetries
M. Hirai, S. Kumano, N. Saito
Global analysis has been performed within the next-to-leading order in Quantum Chromodynamics (QCD) to determine polarized parton distributions with new experimental data in spin a…
Global analysis of AAC for determining polarized parton distribution functions
M. Hirai, S. Kumano, N. Saito
We report global analysis results for polarized parton distribution functions in the nucleon. The optimum distributions are determined by using spin asymmetry data on polarized lep…
AAC analysis of polarized parton distributions with uncertainties
M. Hirai, S. Kumano, N. Saito
We report recent studies of the Asymmetry Analysis Collaboration (AAC) on polarized parton distribution functions (PDFs). Using the data on the spin symmetry A_1 in deep inelastic…
