Scaled Momentum Spectra in Deep Inelastic Scattering
Charged particle production has been studied in deep inelastic scattering (DIS) using an integrated luminosity of about 0.44 fb−1 taken with the ZEUS detector at HERA. The fragmentation properties of the struck quark in deep inelastic scattering have been investigated in the current fragmentation region of the Breit frame as a function of the exchanged boson virtuality Q. The measured evolution...
متن کاملProbing QCD-instanton induced effects in deep inelastic scattering at HERA
After a brief introduction into the phenomenology of instantons, results from instanton perturbation theory applied to deep-inelastic electron proton scattering are summarized. Based on event signatures derived from Monte Carlo studies, strategies for enhancing instanton induced events relative to Standard Model deep-inelastic events are developed. Preliminary results for a search for such even...
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 کاملQCD Instanton-induced Processes in Deep-inelastic Scattering - Search Strategies and Model Dependencies
We investigate possible search strategies for QCD-instanton induced processes at HERA in the deep-inelastic scattering (DIS) regime. Our study is based on the Monte Carlo generator QCDINS for instanton-induced events and the standard generators for normal DIS events. It appears possible to isolate an instanton enriched data sample via an optimized multi-dimensional cut scenario for a set of six...
متن کاملSubtraction method for NLO corrections in Monte-Carlo event generators for leptoproduction
In the case of the gluon-fusion process in deep-inelastic leptoproduction, I explicitly show how to incorporate NLO corrections in a Monte-Carlo event generator by a subtraction method. I calculate the parton densities to be used by the event generator in terms of MS densities. The method is generalizable. A particular motivation for treating the gluon-fusion process is to treat diffractive dee...
