The 17th Workshop of the LHC Higgs Working Group - ONLINE ONLY

→ Europe/Zurich
Online only

Online only
Description

      The LHC Higgs cross-section working group (HXSWG) was created in January 2010. The aim of this group was to produce agreements 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 property/measurement and BSM extensions. Four CERN Reports have been completed, "Inclusive Observables" (CERN-2011-002), "Differential Distributions" (CERN-2012-002),  "Higgs Properties" (CERN-2013-004) and "Deciphering the nature of the Higgs Sector" (CERN-2017-002).  This 17th general meeting will be an occasion to decide the future direction of the group.

Due to evolving and uncertain situation with the novel coronavirus outbreak, the format of this meeting will be online only. This year we would like to stay safe, reduce travel, and potentially reach wider audiences.
