Charm fragmentation at HERA
نویسنده
چکیده
Recent data on charm fragmentation, collected and analyzed by the H1 and ZEUS collaborations, are reviewed and compared with a results from e + e − experiments. The measured fragmentation ratios and fragmentation fractions are in agreement with those measured in e + e − , thus supporting the assumption of universality. Results on the structure of charm jets are presented. The normalized differential cross section of D *-mesons as a function of fragmentation sensitive observables has been measured and used to extract fragmentation function parameters. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

Charm fragmentation and excited charm and charm-strange mesons at ZEUS
Charm hadrons were produced copiously in ep collisions with a centre-of-mass energy of 318GeV at HERA providing a means to study charm hadronisation. During first phase of the HERA operation (1992-2000), the ZEUS collaboration accumulated data sample corresponding to an integrated luminosity of ∼ 120 pb. Measurements of the D, D, D and Λc production a with the HERA I data were used to determine...
متن کاملJ/ψ production via fragmentation at HERA
We compute the contributions to large-pT J/ψ production at HERA coming from fragmentation of gluons and charm quarks. We find that the charm quark fragmentation contribution dominates over the direct production of J/ψ via photon-gluon fusion at large-pT , while the gluon fragmentation is negligibly small over the whole range of pT . An experimental study of pT distributions of J/ψ at HERA will ...
متن کاملOpen charm production at HERA
Inclusive charm meson production cross sections in the deep inelastic scattering and photoproduction regimes are compared with QCD leading and next-to-leading order (NLO) calculations. The NLO predictions are significantly below the data in some parts of the measured kinematic range. Angular distributions of dijet events with charm show clear evidence for the existence of charm originating from...
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 کاملCharm Hadronisation in Γp Collisions with Zeus at Hera
The measured D, D, D, D s and Λ c photoproduction cross sections have been used to determine charm fragmentation ratios and fractions of c quarks hadronising as a particular charm hadron, f(c → D,Λc). Events with a D meson produced in association with an energetic jet have been used to measure the charm fragmentation function. The results are compared with different models and with previous mea...
متن کاملHeavy Flavour Production at Hera
A selection of topics on open heavy quark production at HERA are reviewed here. Measurements of charm fragmentation parameters will be presented together with developments in the study of D di-jet angular distributions. Charm production in deep inelastic scattering (DIS) is also discussed. Finally we deal with recent measurements of b cross sections using impact parameters in both DIS and photo...
