Muon Collider Physics at Very High Energies
Muon colliders might greatly extend the energy frontier of collider physics. One can contemplate circular colliders with center-of-mass energies in excess of 10 TeV. Some physics issues that might be relevant at such a machine are discussed.
متن کاملHeavy Flavour Production at Hera
The production of charm and beauty quarks in ep collisions at HERA has been studied by the H1 and ZEUS collaborations. Charm production is generally well described in total rate and in shape by next to leading order (NLO) calculations in perturbative quantum chromodynamics (QCD), although in specific phase space corners the NLO calculations underestimate the observed cross sections. More and mo...
متن کاملHeavy Flavour Production at HERA
Measurements of charm production in lepton-proton collisions at a centre-of-mass energy of p s = 300 GeV performed at HERA by the experiments H1 and ZEUS are reviewed. Final states containing charm are mainly identiied by reconstruction of D and J= mesons. The results cover the region in 4-momentum transfer squared Q 2 , from photoproduction (Q 2 0) to deep-inelastic scattering at high Q 2. The...
متن کاملHeavy Flavour Production at Hera
A selection of topics on open heavy quark production at HERA are reviewed here. Measurements of charm fragmentation parameters will be presented together with developments in the study of D di-jet angular distributions. Charm production in deep inelastic scattering (DIS) is also discussed. Finally we deal with recent measurements of b cross sections using impact parameters in both DIS and photo...
متن کاملHeavy Flavour Production at Hera
Recent measurements of Charm and Beauty production at HERA are described. The charm results are well described by NLO QCD calculations with a somewhat better description in the CCFM than in the DGLAP evolution schemes. However, the Beauty results in both photoproduction and in deep inelastic scattering (DIS) are poorly described by such calculations.
