- This is the survey for all accessible SM processes at RUN-2, HL-LHC and beyond. BSM Higgs will be discussed elsewhere in new LHCHXSWG structure.


In January 2010, a new joint effort for Higgs cross sections between ATLAS, CMS and theory community was announced and the new LHC wide working group has been created. The aim of this group is to produce agreements on cross sections, branching ratios and pseudo-observables relevant to SM and MSSM Higgs boson(s), which will facilitate comparison and combination of results. This will require the active collaboration of the leading theorists developing the tools with experimental collaborations.
In Spring 2012, the group has been restructured and new subgroups were added where the Higgs property measurement phenomenological issues and BSM theoretical issues will be discussed. The nomination of new theory overall contacts agreed between ATLAS and CMS has been documented. New structure and contact persons have been identified and the LoI for 2012-2014 activity has been submitted. The overall contact persons from ATLAS, CMS and theory community and contact persons for subgroups have been appointed for 2-year mandate starting from April 1st, 2012. The contacts will report the progress to each Higgs working groups.
The group is an open forum and all interested parties are invited to contribute. The results posted are under the responsibility of the subgroup and of the overall contacts of LHC Higgs XS WG. Nevertheless ATLAS/CMS and the LHC Higgs XS WG respect the scientific value of original works performed outside the group. ATLAS/CMS have sole responsibility on citing work done within the LHC Higgs XS WG or not, but do not guarantee that the actual numbers used in the analyses will include results which have been produced outside the LHC Higgs XS WG. One also should keep in mind that this group is not a forum for general discussion on Higgs physics. Unreleased data results from the collaborations will not be shown nor discussed in this group.
If you want to join any of the subgroup, please send an e-mail to subgroup contacts listed below as well as to the overall contacts. Please subscribe yourself to the mailing list lhc-higgs.

Figure 1: Standard Model Higgs boson production cross sections at Ecm = 7 and 8 TeV. Transition for VBF at MH=300 GeV at 8 TeV is due to change from ZWA to complex-pole-scheme. Right hand plot shows the total cross sections for Ecm = 7, 8 and 14 TeV.

Figure 2: Standard Model Higgs boson decay branching ratios and total width.

Figure 3: Standard Model Higgs boson production cross section times branching ratio at Ecm= 8 TeV. For H→ττ both inclusive (solid line) and VBF (dashed line) mode are plotted.
