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 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.
متن کاملGeneralized parton distributions from lattice QCD.
We perform a quenched lattice calculation of the first moment of twist-two generalized parton distribution functions of the proton, and assess the total quark (spin and orbital angular momentum) contribution to the spin of the proton.
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 کاملDiffractive parton distributions from H 1 data
We analyse the latest H1 large rapidity gap data to obtain diffractive parton distributions , using a procedure based on perturbative QCD, and compare them with distributions obtained from the simplified Regge factorisation type of analysis. The diffractive parton densities and structure functions are made publically available. The H1 Collaboration have recently released measurements of diffrac...
