Workshop on top physics at the LC 2017

7 Jun 2017, 08:30 → 9 Jun 2017, 18:00 Europe/Zurich

503/1-001 - Council Chamber (CERN)

Philipp Roloff (CERN)

The workshop on top physics at the LC 2017 will gather theorists and experimentalists to study the potential of future lepton colliders in the area of top quark physics. Sessions will be devoted to precision measurements of the top quark properties including its mass and couplings to the bosons of the Standard Model. Other sessions will cover BSM searches with top quarks, top quark reconstruction techniques, relevant Monte Carlo event generators and tools for theory calculations. In 2017, the workshop on top physics at the LC will take place at CERN between June 7 and 9. Previous workshops in this series have been held in Paris (2014), Valencia (2015) and Tsukuba (2016). The agenda of the workshop will be developed by a program committee. The members of this program committee are: Keisuke Fujii (KEK), Andre Hoang (Vienna), Michael Peskin (SLAC), Roman Poeschl (LAL Orsay), Philipp Roloff (CERN), Frank Simon (MPI Munich), Marcel Vos (Valencia) and Andrea Wulzer (CERN).
