LHC EW precision sub-group meeting

Wednesday 20 Jun 2018, 00:00 → 20:30 Europe/Zurich

4/3-006 - TH Conference Room (CERN)

The focus of this meeting will be twofold:
a) follow up on the April and May workshops for the morning session to be held in room 222-R-003 from 9h00 to 13h00.
b) prepare the three reports to the general LHC SM working group meeting on the 21-22nd of June: one on experimental combinations of the weak mixing angle and of the W-boson mass, one on QED/EW theoretical and modelling issues related to predicting the DY observables used for precision measurements at the LHC, and one on QCD issues related to the modelling of W/Z DY production at the LHC.

00:00 → 13:00 Follow up and progress from April and May workshops on s2w and mW: LHC EW precision sub-group meeting
