Parton Distributions from Lattice QCD
We extract the x dependence of the valence nonsinglet u − d distribution function in the nucleon from the lowest few moments calculated on the lattice, using an extrapolation formula which ensures the correct behavior in the chiral and heavy quark limits. We discuss the implications for the quark mass dependence of meson masses lying on the J P C = 1 −− Regge trajectory.
متن کاملUnintegrated double parton distributions
We present the construction of unintegrated double parton distribution functions which include dependence on transverse momenta of partons. We extend the formulation which was used to obtain the single unintegrated parton distributions from the standard, integrated parton distribution functions. Starting from the homogeneous part of the evolution equations for the integrated double parton distr...
متن کاملExtraction of Parton Distributions from Lattice Qcd
We review the calculation of moments of both the polarized and unpolarized parton distribution functions of the nucleon in lattice QCD, and in particular their extrapolation to the physical region. We also discuss the reconstruction of the x dependence of the valence quark distributions in the nucleon from a finite number of lattice moments.
متن کاملGlobal QCD Analysis of Parton Distributions
Recent global QCD analyses of high energy lepton-hadron and hadron-hadron interactions are reviewed. New data on asymmetries in Drell-Yan and W-lepton-asymmetry processes contribute to better determine the d=u ratio; while improved experimental data on inclusive jet production, in conjunction with precise deep inelastic scattering data, place good constraints on the gluon over a wide range of x...
متن کاملUnderstanding Parton Distributions from Lattice QCD
I examine the past lattice QCD calculations of three representative observables, the transverse quark distribution, momentum fraction, and axial charge, and emphasize the prospects for not only quantitative comparison with experiment but also qualitative understanding of QCD.
