ZEUS at the HERA Accelerator )
Production of electroweak vector bosons W and Z in electron-proton collisions at centre of mass energy ps = 300GeV was studied. The data sample used corresponds to the integrated luminosity L = 37:4 pb 1 collected in the ZEUS experiment at HERA during 1993{1997. Hadronic decay channel of W=Z bosons with high transverse energy (High-ET ) nal states was investigated, looking for an excess of even...
متن کاملParticle production at HERA
H1 has measured a number of different known particles and compared their production to QCD models and to other reactions such as N-N collisions. ZEUS has also measured the production of K SK 0 S pairs with a view to searching for glueballs. Several resonances are seen which are glueball candidates. The results on the masses and widths are compared to other experiments. At HERA acceleration ring...
متن کاملParticle Production at Hera ∗
Particle production has been studied in ep collisions with the H1 and ZEUS detectors at HERA. Charged particle spectra were measured in deep inelastic scattering. Predictions from Monte Carlo generators with different models of parton evolution were compared to the data. The production of the neutral strange hadrons K S and Λ 0 was measured and was used to test various fragmentation models. Nex...
متن کاملParticle production at HERA
Recent results on the properties of the hadronic final state at the HERA collider are presented. Strangeness production and correlations have been studied in the laboratory system for deep inelastic scattering (DIS). Inclusive K0 S , Λ and Λ̄ production has been measured and compared to Monte Carlo model calculations. No significant Λ to Λ̄ production asymmetry was observed and the measured Λ(Λ̄) ...
متن کاملSoft Particle Production at Hera
HERA data on soft hadron production are discussed. The measured inclusive and exclusive hadron cross sections show a simple scaling behaviour. The final state hadrons produced in collision of high energy particles carry information about the underlying dynamics of the interaction. Different theoretical approaches have been adopted to describe such hadroproduction. Generally , the applicability ...
