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…
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…
Determination of polarized parton distribution functions and their uncertainties
M. Hirai, S. Kumano, N. Saito
We investigate the polarized parton distribution functions (PDFs) and their uncertainties by using the world data on the spin asymmetry A_1. The uncertainties of the polarized PDFs…
