0 S resonance production in ep collisions at HERA ZEUS
Inclusive K SK 0 S production in ep collisions at HERA was studied with the ZEUS detector using an integrated luminosity of 0.5 fb. Enhancements in the mass spectrum were observed and are attributed to the production of f2(1270)/a 0 2(1320), f ′ 2(1525) and f0(1710). Masses and widths were obtained using a fit which takes into account theoretical predictions based on SU(3) symmetry arguments, a...
متن کاملSearch for Single Top Production in ep Collisions at HERA ∗
In this talk a search for the single production of top quarks performed at the H1 experiment is presented. No evidence for anomalous top production via FCNC processes is found and limits on the anomalous magnetic coupling constant κtuγ are given.
متن کاملLeading neutron production in ep collisions at HERA
The production of neutrons carrying at least 20% of the proton beam energy (xL > 0.2) in e+p collisions has been studied with the ZEUS detector at HERA for a wide range of Q2, the photon virtuality, from photoproduction to deep inelastic scattering. The neutron-tagged cross section, ep → eXn, is measured relative to the inclusive cross section, ep → eX, thereby reducing the systematic uncertain...
متن کاملSpectroscopy in Ep Collisions at Hera
Recent spectroscopy studies performed in high energy ep collisions by the H1 and ZEUS Collaborations are described. The status of the searches for the strange pentaquark, the θ + , is presented as well as results on searches for further exotic states such as the Σ −−. The evidence for the observation of a pentaquark state containing the charmed quark, the θ c , is discussed and the result is gi...
متن کاملInclusive 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...
