ZPW2020 - The Higgs boson and the Top quark

13 Jan 2020, 08:00 → 15 Jan 2020, 16:00 Europe/Zurich

KOL-G-217 (University of Zurich)

The top quark is the heaviest elementary particle in the Standard Model and it is expected to play a special role in the spontaneous breaking of the Electroweak symmetry. In 2018 ATLAS and CMS have announced the first evidence of the associated production of the Higgs boson with a top-quark pair. The workshop will provide a forum for precision studies of top and Higgs boson production, application of Effective Field Theory in the top and Higgs sectors, BSM modeling for top-quark couplings, possible new directions in the study of theory uncertainties in top and Higgs boson measurements.

The workshop, organized jointly by the particle theory groups of UZH and ETH with the support of the Pauli Center for Theoretical Studies, will be held on January 13-15, 2020.
