LHC TOP WG meeting

19 May 2021, 14:00 → 21 May 2021, 16:00 Europe/Zurich

Zoom mtg only (CERN)

Fabio Maltoni (Universite Catholique de Louvain (UCL) (BE) and Università di Bologna), Maria Aldaya Martin (DESY), Michelangelo Mangano (CERN), Reinhard Schwienhorst (Michigan State University (US)), Wolfgang Wagner (Bergische Universitaet Wuppertal (DE))

This periodic open meeting of the LHC TOP Working Group takes place twice a year at CERN. The meeting provides a forum for discussion between experimentalists and theorists on the latest developments in top quark physics. Everybody is welcome to attend; please register using the link on the left. 

Due to the Covid-19 pandemic, the meeting will take place remotely via zoom.
