Hard Processes in Electron-proton Scattering

This report summarizes some of the recent HERA results obtained by studying hard processes in ep–scattering. By resolving the structure of the proton, hard ep– reactions provide information on the parton content of the proton and may give insight into the dynamics of the exchanged parton cascade. In addition, their study offers the possibility to test the Standard Model, in particular perturbat...

Space-time structure of deep-inelastic lepton-hadron scattering.

We discuss the space-time structure of deep inelastic scattering in the target rest frame. At small zbj, the process is dominated by quark pair production, and the " Ioffe time " between the production of the pair and its interaction in the target is long. We compute the leading logarithmic corrections to the parton model predictions for the virtual photo-absorption cross section, and analyze t...

Structure of Hadrons in Hard Processes

In these lectures I want to discuss how the structure functions in deep inelastic scattering relate to quark and gluon correlation functions. In particular we will consider the issue of intrinsic transverse momenta of quarks, which becomes important in processes like 1-particle inclusive leptoproduction. Some examples of cross sections and asymmetries, in particular in polarized scattering proc...

He Structure from Coherent Hard Exclusive Processes

Hard exclusive processes, such as deep electroproduction of photons and mesons off nuclear targets, could give access, in the coherent channel, to nuclear generalized parton distributions (GPDs). Here, a realistic microscopic calculation of the unpolarized quark GPD H3 q of the 3He nucleus is reviewed. In Impulse Approximation, H3 q is obtained as a convolution between the GPD of the internal n...

Soft-gluon corrections in hard-scattering processes through NNNLO

I discuss soft-gluon corrections in hard-scattering processes and their re-summation. I present master formulas for the expansion of the resummed cross section through NNNLO and discuss the significance of these corrections in a number of processes.
