Including heavy quark production in ZEUS-PDF fits
نویسنده
چکیده
At HERA heavy quarks may contribute up to 30% of the structure function F2. The potential of including heavy-quark data in the ZEUS PDF fits is explored, using D∗ double differential cross-sections as well as the inclusive quantities F cc̄ 2 , F cc̄ 2 . The introduction of heavy quarks requires an extension of the DGLAP formalism. The effect of using different heavy flavour number schemes, and different approaches to the running of αs, are compared.

Abstract At HERA heavy quarks may contribute up to 30% of the structure function F2. The introduction of heavy quarks requires an extension of the DGLAP formalism. The effect of using different heavy flavour number schemes, and different approaches to the running of αs, are compared using the ZEUS PDF fit formalism. The potential of including charm data in the fit is explored, using D double di...
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 کاملElectroweak Measurements from Hera
New preliminary electroweak results from the HERA lepton-proton collider experiments H1 and ZEUS are presented. These include new high Q neutral current cross section measurements, limits on a possible quark radius in the search for contact interactions as well as on quark-Z coupling parameters, extracted in combined electroweak and QCD fits. Furthermore, new charged current cross section measu...
