Top quark physics at lepton colliders

15 mai 2012, 13:00 → 16 mai 2012, 17:00 Europe/Zurich

Amphitheatre Chaudron (Paris)

The top quark is the by far heaviest known elementary particle so far. In the heavy quark sector Standard Model predictions are less consistent than in other sectors. With a top quark mass of about 175 GeV, top quark studies are highly relevant topics for any lepton collider which will be operated at centre-of-mass energies between the t tbar threshold and about one 1 TeV. The workshop aims to bring together theorists and experimentalists to discuss the potential for the discovery of new physics given the high precision which can be expected at a future lepton collider. The workshop precedes the European town hall meeting and therefore on the second day other topics of major interest for a lepton collider in the mentioned energy range will be discussed.
