Heavy Flavour Production with Leptons and Hadrons
The production of charm and beauty quarks in γγ collisions at LEP, ep collisions at HERA and p¯ p collisions at the Tevatron is discussed. The comparison with predictions of next-to-leading-order QCD and the issues it raises are detailed. In particular, the strengths and weaknesses of the measurements and predictions are discussed.
متن کاملLifetimes of Heavy-flavour Hadrons – Whence and Whither?
A theoretical treatment for the weak decays of heavy-flavour hadrons has been developed that is genuinely based on QCD. Its methodology as it applies to total lifetimes and the underlying theoretical issues are sketched. Predictions are compared with present data. One discrepancy emerges: the beauty baryon lifetime appears to be significantly shorter than expected. The ramifications of those fi...
متن کاملThe Qcd Perspective on Lifetimes of Heavy-flavour Hadrons
Over the last few years a theoretical treatment for the weak decays of heavy-flavour hadrons has been developed that is genuinely based on QCD. Its methodology is described as it applies to total lifetimes, and the underlying theoretical issues are discussed. Theoretical expectations are compared with present data. One discrepancy emerges: the beauty baryon lifetime appears to be significantly ...
متن کاملHeavy Flavour Production
I review recent developements in the theory of heavy flavour production. In particular, I dicuss the next-to-leading resummation of soft gluon effects in heavy flavour hadroproduction, and the next-to-leading resummation of collinear radiation in the production of heavy flavour at large transverse momenta. 1 Talk presented at the 12 Rencontre de Physique de la Valle d’Aoste, La Thuile, March 19...
متن کاملHeavy flavour in ALICE
ALICE [1, 2] is the dedicated heavy-ion experiment at the Large Hadron Collider (LHC). The main physics goal of the experiment is the study of strongly-interacting matter in the conditions of high energy density (> 10 GeV/fm) and high temperature (> ∼ 0.2 GeV), expected to be reached in central Pb–Pb collisions at √ sNN = 5.5 TeV. Under these conditions, according to lattice QCD calculations, q...
