Charm production at HERA
نویسنده
چکیده
The HERA collider circulates beams of electrons (positrons) and protons at energies of 27.5 and 820GeV respectively. The ep centre of mass energy for collisions between the beams is 300GeV. The largest cross-section processes observed in these collisions are photoproduction reactions, where the e beam acts as a source of almost real (Q ≪ 1GeV) photons. Processes where a virtual photon of sizeable Q is exchanged are known as Deep Inelastic Scattering, or DIS reactions. In this paper I review measurements of open charm production at HERA made in both photoproduction and DIS by the H1 and ZEUS collaborations.

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 ...
