Workshop on Top physics at the LC

5 Mar 2014, 13:30 → 6 Mar 2014, 13:30 Europe/Paris

12-22-RC-08 (LPNHE Paris)

Top quark production in the process e+e--> tt at a future linear electron positron collider with polarised beams is a powerful tool to determine the scale of new physics. Studies at the tt threshold will allow for precise determination of the top quark mass in a well defined theoretical framework. At higher energies vector, axial vector and tensorial CP conserving couplings can be separately determined for the photon and the Z^0 component in the electroweak production process. The direct observation of tth in the clean environment of e+e- collisions is another asset of the Linear Collider physics program. The full exploitation of the potential of top quark physics at the Linear Collider requires a very close collaboration between theoretical and experimental groups over the coming years. The workshop will bring together experts working in the field with the aim to contribute to a structured approach to the open questions. The workshop is jointly organised by LPNHE Paris and LAL Orsay by these people Emi Kou, François LeDiberder, François Richard, Dirk Zerwas, Didier Lacour and Roman Pöschl The programme committee is composed by Keisuke Fuji (KEK, keisuke.fujii@kek.jp), Wolfgang Hollik (MPP Muenchen, hollik@mpp.mpg.de), Didier Lacour (LPNHE Paris, Didier.Lacour@cern.ch) and Marcel Vos (IFIC Valencia, Marcel.Vos@cern.ch) NEW 27/7/14!!!!
