Inclusive Hadron Production and Dijets at Hera
The HERA storage ring provides beams of protons at 820 GeV and positrons at 27.5 GeV energy. Collisions of these are recorded at two general purpose detectors, H1 and ZEUS. Measurements of the hadronic final state in deepinelastic scattering and in photoproduction processes allow precise tests of the validity of perturbative Quantum-Chromo Dynamics (pQCD). In addition the extraction of the stro...
متن کاملStrangeness Production and Hadron Spectroscopy at HERA
An overview of the recent results on strangeness production and spectroscopy from the electron-proton collider experiments H1 and ZEUS at HERA is presented. Production of particles with light and strange quarks is discussed and compared with both theoretical predictions and with data from ee experiments. Measurements in the charm sector cover studies of the radially and orbitally excited charm ...
متن کاملHadron Spectroscopy at Hera
on behalf of the ZEUS and H1 Collaborations Inclusive photoproduction cross-sections of the neutral mesons η, ρ 0 , f 0 (980) and f 2 (1270) have been measured by H1 and compared to the photoproduction of π + in ep collisions at HERA. Also, inclusive K 0 s K 0 s production and evidence for a narrow baryonic state decaying to K 0 s p have been observed by ZEUS at HERA.
متن کاملPerturbative description of inclusive single hadron production at HERA
Abstract Light charged hadron production data in the current fragmentation region at HERA are calculated using next-to-leading order perturbative calculations and fragmentation functions obtained from similar data from e+e− reactions. General good agreement is found at large photon virtuality Q2 and intermediate momentum fraction xp, consistent with fragmentation function universality. The desc...
متن کاملDijet Production at HERA in Next-to-Leading Order
Two-jet cross sections in deep inelastic scattering at HERA are calculated in next-to-leading order. The QCD corrections are implemented in a new ep → n jets event generator, MEPJET, which allows to analyze arbitrary jet definition schemes and general cuts in terms of parton 4-momenta. First results are presented for the JADE, the cone and the kT schemes. For the W -scheme, disagreement with pr...
