LHC EW WG General Meeting

10 Jul 2024, 09:00 → 12 Jul 2024, 18:00 Europe/Zurich

40/S2-C01 - Salle Curie (CERN)

Alessandro Tricoli (Brookhaven National Laboratory (US)), Guillelmo Gomez Ceballos Retuerto (Massachusetts Inst. of Technology (US)), Oldrich Kepka (Czech Academy of Sciences (CZ)), Vieri Candelise (Universita e INFN Trieste (IT))

This General LHC EW Meeting will review the progress in Standard Model phsyics at the LHC, the activities of the LHC EW working groups, and especially will plan future activities of the group with the goal to set reccomendations for future precision measurements at the LHC.

If you work on Standard Model analyses at the LHC or plan to carry out precison physics measurements with Run-3 data, join the meeting and bring your contribution to the discussions and planning.
