Hera ∗
Over the past few years, great progress has been achieved in the understanding of the hadronic final state and of jet production at HERA. This is, for example, expressed in the extremely good description of jet cross-sections at high values of the photon virtuality, Q, or the precise determinations of the strong coupling parameter, αS , from jet data. At present, our best knowledge is contained...
متن کاملResonance Searches at HERA
Inclusive production of K SK 0 S in ep collisions was studied with the ZEUS detector. Significant production of J = 2 tensor mesons and of the 0 glueball candidate f0(1710) was seen. Masses and widths were compared with previous experiments. The H1 Collaboration saw a charm pentaquark candidate in the D∗p spectrum at 3.1 GeV, which was not confirmed by a ZEUS higher statistics search. With the ...
متن کاملInclusive Diffraction at Hera
New precision measurements of inclusive diffractive deep-inelastic ep scattering interactions, performed by the H1 and ZEUS collaborations at the HERA collider, are discussed. A new set of diffractive parton distributions, determined from recent high precision H1 data, is presented.
متن کاملJet photoproduction at HERA
We compute various kinematical distributions for one-jet and two-jet inclusive photoproduction at HERA. Our results are accurate to next-to-leading order in QCD. We use the subtraction method for the cancellation of infrared singularities. We perform a thorough study of the reliability of QCD predictions; in particular, we consider the scale dependence of our results and discuss the cases when ...
