LHC EW WG Conveners
Description

This General LHC EW Meeting will review the progress in Standard Model physics at the LHC, the activities of the LHC EW working groups, and will plan future activities of the group to set recommendations for future precision measurements at the LHC:

  1. EW WG1: Precision EW
  2. EW WG2: EW bosons & Jets
  3. EW WG3: Multibosons

Specifically, this meeting will continue the discussions we started in the previous meeting in November.

We hope you can join the meeting and bring your contribution to the discussions and planning. The workshop will be held in person at CERN, with a zoom connection available for remote participation. Please register through the registration button to help us find an adequate room.

We will start on Monday, 30 March, after lunchtime, to allow for travel to CERN in the morning. Our meeting will end on Wednesday, 1 April, in the late afternoon, so you can catch an evening flight back home.
