News about CERN TH and its activities are listed on the home page of this website (http://cern.ch/ph-dep-th). Members of the group are assumed to be aware of all official announcements made there.
The group's TH Theoretical Seminar is a weekly colloquium of general interest for particle physicists, and attendance is expected for all members and visitors of TH. It takes place on Wednesdays at 2pm and is usually video recorded. For detailed information on all seminar series, TH Institutes, workshops, etc., see the respective links above.
The coming week's seminars are also announced by email every Friday from the TH seminar address. Everyone registered with CERN as being part of the TH unit receives those mails. External people can ask to receive the announcements also, simply by subscribing to the e-group th-unit-invited. Seminar posters are to be found on the notice board in the Common Room (Bldg. 4-2.011, ) Bldg. 53-1.075 and Bldg. 50 near the library.
In addition, there are also more informal gatherings: weekly lunches to discuss the latest news in BSM (Thursdays) and collider QCD (Tuesdays), the TH Picnic in the autumn to welcome new arrivals, and the TH Christmas Party. The group usually also holds off-campus a TH Retreat once a year, to facilitate integration of new members of CERN TH.
