The LHC Higgs Working Group was created in January 2010 under the name "LHC Higgs Cross Section Working Group."
Its aim was to produce agreements within the LHC community on cross sections, branching ratios and pseudo-observables relevant to SM and MSSM Higgs boson(s).
In spring 2012, the group was restructured and new subgroups were added with the goal of discussing Higgs properties and measurements, as well as BSM extensions. A further restructuring took place in 2014, when the
TAC (Theory Advisory Committee) was added to the organization, and
an agreement was made with CERN for local support. The TAC always includes one permanent member of the CERN theory group. The activities of the group are supervised by the
Steering Committee (SC) that includes two representatives from each experiment and four representatives from the theory community. The SC members from ATLAS or CMS are appointed by each experiment after their internal selection procedures. The SC members from the theory community are appointed by the TAC, in coordination with the SC.
Over time, the focus of the working group has widened substantially, so that in November 2020, the majority of its members decided to adjust the name to "LHC Higgs Working Group".”
