LHC Electroweak Multiboson Subgroup

This public page documents relevant discussions and results in the Multiboson subgroup of the LHC electroweak group.

Organization of the Group

The activities of the group are organised by subgroup conveners:

• ATLAS: Joany Manjarres Ramos, Kristin Lohwasser, Shu Li
• CMS: Philip Chang, Roberto Covarelli, Pietro Vischia
• Theory: Jonas Lindert and Celine Degrande
• Send mail to conveners

The activities of the group include:

• Discussion on theory developments in the multiboson area and their implications on the experimental measurements
• Discussion on common methodologies for the LHC multiboson measurements
• Efforts to provide guidelines on the common fiducial definitions for furture LHC multiboson measurements
• Production of ATLAS+CMS summary plots on anomalous coupling limits and on multiboson cross-section measurements
• Combination of limits on anomalous gauge boson couplings from ATLAS and CMS
