Heavy Quarks in Elect’roproduction*
The idea of an effective light-particle field theory is used to analyze the effects of heavy quarks in electroproduction. The b-quark distribution is predicted at large QL and a systematic treatment of the changing number of quark flavors in a QCD analysis of F2 is presented. Submitted to Nuclear Physics B. * Work supported in part by the Department of Energy under contract DE-AC03-76SF00515. +...
متن کاملHeavy Quarks in Quantum Chromodynamics
A pedagogical introduction to the heavy quark theory is given. It is explained that various expansions in the inverse heavy quark mass 1=mQ present a version of the Wilson operator product expansion in QCD. A systematic approach is developed and many practically interesting problems are considered. I show how the 1=mQ expansions can be built using the background eld technique and how they work ...
متن کاملInto Heavy Quarks *
We measure the hadronic branching ratios of the Z boson into heavy quarks: Rb = ΓZ0→bb/ΓZ0→hadrons and Rc = ΓZ0→cc/ΓZ0→hadrons using a multi-tag technique. The measurement was performed using about 400,000 hadronic Z events recorded in the SLD experiment at SLAC between 1996 and 1998. The small and stable SLC beam spot and the CCD-based vertex detector were used to reconstruct bottom and charm ...
متن کاملRadiation of Heavy Quarks
The rate for the production of massive fermions radiated off a pair of massless fermions is calculated analytically. Combined with the analytic calculation of the corresponding virtual contribution one obtains the order α 2 correction to the cross section which is induced by the real and virtual radiation of a pair of massive fermions by massless fermions. Approximations valid for large and for...
متن کاملFrom Glasma to Quark Gluon Plasma in heavy ion collisions
When two sheets of Color Glass Condensate collide in a high energy heavy ion collision, they form matter with very high energy densities called the Glasma. We describe how this matter is formed, its remarkable properties and its relevance for understanding thermalization of the Quark Gluon Plasma in heavy ion collisions. Long range rapidity correlations contained in the near side ridge measured...
