Parametrization of polarized parton distributions
We report the polarized parton distributions proposed by the Asymmetry Analysis Collaboration (AAC). Using parametrized distributions at Q 2 =1 GeV 2 and measured A1 data, we determine optimum polarized distributions in the leading order (LO) and next-to-leading order (NLO). We find that the polarized antiquark distribution is not well determined particularly at small x. It could lead to a rath...
متن کاملPolarized Parton Distributions for Spin Asymmetries
We have used QCD and polarized deep-inelastic scattering data to construct xdependent polarized parton distributions. These flavor dependent distributions evolve under the NLO DGLAP equations, satisfy positivity constraints and agree well with the data. We perform all of the analysis in x-space, avoiding difficulties with moments, and use these distributions to predict spin observables. The sma...
متن کاملPolarized Parton Distributions: Theory and Experiments
We have extracted the constituent contributions to the spin of the proton from recent data at CERN, SLAC and DESY. The valence, sea quark and antiquark spin-weighted distributions are determined separately. The data appear to imply a small to moderate polarized gluon distribution, so that the anomaly term is not significant in determining these contributions. We have analyzed the consistency of...
متن کاملPolarized Parton Distributions in Light-front Dynamics
We present a consistent calculation of the structure functions within a light-front constituent quark model of the nucleon. Relativistic effects and the relevance of the covariance constraints are analyzed for polarized parton distributions. Various models, which differ in their gluonic structure at the hadronic scale, are investigated. The results of the full covariant calculation are compared...
متن کاملPolarized Parton Distributions and QCD Analysis
In this talk we summarize main results of a recent determination of the polarized deeply inelastic parton distributions to NLO from the world data. In the analysis the LO and NLO parton densities and their 1σ statistical errors were derived and parameterized. The strong coupling constant αs(M 2 Z) is determined αs(M 2 Z) = 0.113±0.004(stat.)± 0.004(fac.)+0.008/−0.005(ren.) Comparisons of the lo...
