Qcd Studies in Ep Collisions
These lectures describe QCD physics studies over the period 1992-1996 from data taken with collisions of 27 GeV electrons and positrons with 820 GeV protons at the HERA collider at DESY by the two generalpurpose detectors HI and ZEUS. The focus of these lectures is on structure functions and jet production in deep inelastic scattering, photoproduction, and diffraction. The topics covered start ...
متن کاملCharm Production in Ep-collisions
Recent results on the production of open charm in electron proton scattering at HERA are reviewed. Results on the fragmentation of charm are presented and compared to the measurements at e + e − colliders. Recent results on the charm contribution to the proton structure function F2 are shown. Furthermore, measurements of inclusive D * meson, D * + jet and D * + muon production are presented. Th...
متن کاملJET PRODUCTION IN ep COLLISIONS
The observation of jet production at HERA allows to test the theory of strong interactions, quantum chromodynamics (QCD), and to extract information on the parton content of the proton and of real or virtual photons. QCD predicts the production of partons with large transverse momenta, fragmenting into jets with similar four-momenta. The study of jet observables therefore allows to investigate ...
متن کاملExclusive production of dijets in QCD
We study in a framework of QCD collinear factorization the processes of a pion and a photon diffraction dissociation into two jets. The structure of non-factorizable contributions is discussed. We argue that coherent production of hard dijets by linearly polarized real photons can provide direct evidence for chirality violation in hard processes, the first measurement of the magnetic susceptibi...
متن کاملExclusive Production of Vector Mesons in Qcd
We compare results of our studies [1,2] on vector meson production within the QCD factorization at next-to-leading order with HERA data. 1 Introduction The exclusive vector meson V electro-and photo-productions in photon-proton collisions , γ p → V p, are the subject of HERA collider experiments. The primary motivation for the interests in these processes, both for the light ρ−meson electro-pro...
