Semi-leptonic Decays of Heavy Quarks in Dijet Photoproduction at HERA
نویسنده
چکیده
The production of heavy quarks has been studied in photoproduction processes with the ZEUS detector at HERA using an integrated luminosity of 36.9 pb. Events with a photon virtuality, Q < 1 GeV, were selected with two jets of high transverse energy and an electron in the final state. Consideration of the distribution in p T − the momentum of the electron transverse to the axis of the jet to which the electron is closest − allows a measurement of the beauty cross-section in a restricted region of phase space.

Heavy Flavours in Photoproduction at HERA
Differential cross sections, dσ/dx OBS γ , for dijet photoproduction events with a tagged D * meson are presented, where x OBS γ is the fraction of the photon energy contributing to the two highest transverse energy jets. Results on open beauty cross sections (from semileptonic decays) compared to LO Monte Carlo predictions are also presented. 1 Photoproduction The photon structure is being pro...
متن کاملHard Photoproduction at HERA
In view of possible photoproduction studies in ultraperipheral heavy-ion collisions at the LHC, we briefly review the present theoretical understanding of photons and hard photoproduction processes at HERA, discussing the production of jets, light and heavy hadrons, quarkonia, and prompt photons. We address in particular the extraction of the strong coupling constant from photon structure funct...
متن کاملHeavy Flavor in Photoproduction at HERA
Recent results on charm and beauty photoproduction at HERA are discussed. The perturbative QCD calculations are generally smaller than the measured cross sections, particularly in the forward (proton) direction. The study of charm dijet photoproduction is consistent with a significant contribution of charm excitation processes.
متن کاملMeasurement of beauty photoproduction using decays into muons in dijet events at HERA
Beauty photoproduction in dijet events has been measured at HERA with the ZEUS detector using an integrated luminosity of 126 pb −1. Beauty was identified in events with a muon in the final state by using the transverse momentum of the muon relative to the closest jet. Lifetime information from the silicon vertex detector was also used; the impact parameter of the muon with respect to the prima...

Heavy quarks are copiously produced in two-photon collisions at ee colliders. The theoretical predictions including QCD radiative corrections are compared to recent experimental data on γγ production of charm quarks at PETRA, PEP, TRISTAN and LEP. Photoproduction of heavy quarks at HERA is an important tool to measure the gluon distribution in the proton. New theoretical results on heavy quark ...
