Structure Functions on the Lattice
We report on a lattice computation of the second moment of the pion matrix element of the twist-2 non-singlet operator corresponding to the average momentum of parton densities. We apply a fully non-perturbatively evaluated running renormalization constant as well as a careful extrapolation of our results to the continuum limit. Thus the only limitation of our final result is the quenched appro...
متن کاملHadron Structure Functions from Lattice QCD – 1997
We review the status of lattice calculations of the deep-inelastic structure functions of the nucleon. In addition, we present some results on the pion and rho structure functions.
متن کاملSpin Structure Functions from Lattice QCD ∗
We report on new results of the spin dependent structure functions g 1 and h 1 of the nucleon. An attempt is made to convert the moments, which is what one computes on the lattice, to quark distribution functions.
متن کاملPhoton Structure Functions from Quenched Lattice QCD
We calculate the first moment of the photon structure function, 〈x〉 = ∫ 1 0 dxF γ 2 (x,Q 2), on the quenched lattices with β = 6.0 using the formalism developed by the authors recently. In this exploratory study, we take into account only the connected contractions. The result is compared with the experimental data as well as model predictions. The parton (quark and gluon) distributions in hadr...
متن کاملPolarized structure functions from the lattice
We give a brief sketch of lattice structure function calculations and review previous results for the axial coupling gA. We outline a new technique for treating fermions on the lattice that preserves chiral symmetry, domain wall fermions. Finally, we give preliminary results for the nucleon spectrum using this new technique. Remarkably, a large mass splitting between the N and N∗, roughly consi...
