Factorization Breaking in Dijet Photoproduction with a Leading Neutron

The production of dijets with a leading neutron in ep-interactions at HERA is calculated in leading order and next-to-leading order of perturbative QCD using a pion-exchange model. Differential cross sections for deep-inelastic scattering (DIS) and photoproduction are presented as a function of several kinematic variables. By comparing the theoretical predictions for DIS dijets to recent H1 dat...

We have calculated the fermionic contributions to the flavour non-singlet structure functions in deep-inelastic scattering (DIS) at third order of massless perturbative QCD. We discuss their implications for the threshold resummation at the next-to-next-to-leading logarithmic accuracy.

Three-jet event-shapes in lepton-proton scattering at next-to-leading order accuracy

We compute the differential distributions of two three-jet event-shape observables at the next-to-leading order accuracy at fixed values of the DIS kinematic variables. The observable Kout measures the out-of-event-plane momentum. The other observable y3 is the maximum value of the ycut resolution variable for which an event is classified as three-jet event. We also show the dependence of the f...

Sudakov resummation for prompt - photon production in hadron collisions ∗

We present the explicit expressions for the resummation of large-xT Sudakov effects in the transverse-energy distribution of prompt-photons produced in hadronic collisions, to next-to-leading logarithmic (NLL) accuracy. Fragmentation processes do not contribute to the Sudakov resummation at NLL level. In Mellin space, the resummed radiative factor is the product of independent radiators for eac...
