β¦ Synopsis
We calculate the first moment of the photon structure function, (x)' = si dzF,Y(z,Q2), on the lattice using the formalism developed by the authors. Different lattice spacings and volumes are studied to estimate the systematic errors present in lattice simulations. Also, the Nf = 2 dynamical configurations, generated by SESAM collaboration, are studied for the effect of quark loops on (x)'.

The hadronic photon structure function from the LEP experiments will be reviewed. Since the 1998 Lund meeting new results from the ALEPH, L3 and OPAL collaborations have become available. The LEP data now cover a large range in x and Q2. At high Q2 the agreement with the theoretical predictions gets
A genuinely non-perturbative evaluation of higher-twist contributions to the structure functions of the nucleon, with all mixing effects and renormalon ambiguities taken care of, is presented. Higher-twist corrections turn out to be significant at moderate values of q2.
We present here the latest results from the QCDSF collaboration for (moments of) structure functions and generalized form factors in full QCD with N f = 2 O(a)-improved Wilson fermions based on simulations closer to the chiral and continuum limit.
