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 below. 

The meeting is planned to be hybrid (in-person + zoom).

Meeting rooms
In the course of the meeting we will use three different meeting rooms at CERN.
WEDNESDAY      13:00 - 18:00  CMS center (room 354/1-019)
THURSDAY         10:00 - 12:00 and 13:30 - 18:00   Salle Bohr (room 40/S2-B01)
FRIDAY                13:00 - 15:30    room 160/1-009

Recordings of the sessions will be available below once the meeting is over.
