The LHC Higgs Working Group (LHCHWG) provides recommendations on theoretical predictions and methodologies on Higgs boson(s) studies to the experiments for both current and planned LHC runs. More general aspects related to non-Higgs-boson(s)-specific subjects, like global Effective Field Theories or Dark Matter model studies are pursued by the LHCHWG in collaboration with other more general efforts of the LHC community.

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".”

Four CERN Yellow Reports have been completed:

These achievements facilitated the comparison and combination of Higgs results at LHC since the beginning of the LHC physics programme.

The group is organised into four working groups:

  • WG1: Higgs cross-sections and branching ratios
  • WG2: Higgs properties
  • WG3: BSM Higgs
  • WG4: HH and multi-Higgs

If you want to join the working group, please send an e-mail to working group conveners listed below. Please subscribe to the relevant mailing lists of the group.

Mailing Lists

All members of the working group should subscribe to the general mailing list and the mailing lists for any working groups (and subgroups) they are planning to contribute to.

  • General mailing list
  • Event announcements
  • Mailing lists for each working group (and subgroups) are listed in the Organisation section.
  • How to subscribe to mailing lists
  • Posting messages to any lhc-higgs-xxx list is restricted to members of the lhc-higgs egroup, i.e. you need to use your e-mail account registered to lhc-higgs mailing list.
  • Remove "SPAMNOT" from mailing address when sending.
  • Any new mailing lists should have the prefix "lhc-higgs-". Any TWiki page Topic name should have the prefix "LHCHWG" and should be created under "LHCHWG" Topic parent.


  • Indico category
  • Meeting summaries can be browsed from this page.
  • The SC weekly meeting takes place every Friday 17:00-18:00. Please avoid organising meetings during this time slot if possible.
  • Please make sure to take into account timezone constraints of participants in order to facilitate participation from all regions. Early afternoon in Europe is generally a good compromise to allow participants from Asia and the Americas to connect.


A record of the previous WG convenors and members of the steering committee is being compiled in this spreadsheet. Anyone with historical knowledge of the WG is encouraged to add missing names.
