Charm and Beauty Production at Cdf
The Tevatron at Fermilab is at present the world’s highest energy particle accelerator. After extensive refurbishments, data taking for Run II started in 2001, and by the end of 2003 over 200 pb of usable integrated luminosity had been accumulated by each Collider experiment, double the total for Run I. In preparation for Run II, the CDF detector also underwent an extensive upgrade. Of special ...
متن کاملCharm and Beauty Production and Polarization at Cdf
In this paper we present results on Charm and Beauty production as well as on production and polarization of Quarkonia at p s = 1:8 TeV. These results were obtained from data taken with the CDF detector at Fermilab. We cover recently completed analyses of the 1992-96 collider run.
متن کاملCharm and Beauty Production at HERA–B
The HERA–B experiment at DESY has acquired a data-set of approximately 300,000 decays J/ψ→ l+l− during its 2002/2003 data-taking period. These data are used to analyze the production of heavy quarks in proton-nucleus interactions at a center-of-mass energy of 41.6 GeV. In this article, preliminary results of two measurements are discussed, a measurement of nuclear effects in the production of J...
متن کاملOpen Charm and Beauty Production at Hera
Selected new results from the H1 and ZEUS collaborations on ep interactions at 300-318 GeV centre-of-mass energy are presented. The full pre-upgrade integrated luminosity of HERA of 110 pb −1 is used. Charm cross sections are measured up to high values of x B and Q 2 and are found to be well described by NLO QCD in the 3 flavour scheme. Orbitally excited D mesons are observed; radial excitation...
متن کاملCharm and Beauty Production at HERA with D∗-Muon Events Charm and Beauty Production at HERA with D∗-Muon Events
Heavy quark production (c and b) is investigated in the H1-experiment at the ep collider HERA using events with a D∗-meson and an additional muon. Data taken during the years 1997 and 1999-2000, corresponding to an integrated luminosity of about 85 pb−1, are used. Exploiting the charge and angle correlations between the D∗-meson and the muon a separation of charm and beauty production is perfor...
