Diffraction in DIS

Measurements of heavy-quark production at HERA constrain the structure of the proton, and have provided valuable indications of perturbative QCD.Several measurements of heavy quark production in deep inelastic scattering and photoproductions regimes, using different decay modes, are presented, both new individual measurements from the H1 and ZEUS collaborations, as well as combined data. QCD...

Diffraction in DIS

Exclusive charm vector meson production has been studied in the high statistics HERA-2 data. H1 has measured the elastic and proton-dissociative photoproduction cross sections of J/psi mesons as function of W_{gamma p} and t. The W_{gamma p} and t dependencies are parametrised using phenomenological fits, and results are compared to other measurements. ZEUS has measured the cross...

Diffraction in DIS

The production of inclusive jets as well as of dijet and trijet topologies is investigated with the high statistics HERA II data. The H1 and ZEUS experiments have determined the corresponding cross sections with improved experimental precision, compared to previous measurements. For both experiments, a hadronic energy scale uncertainty as small as 1% is reached. The value of the...
