Probing BSM with the Higgs boson Width at CMS

Many models of new physics predict BSM particles that couple to the Higgs boson. Measurements of the Higgs boson width are a powerful way to probe these new physics scenarios and are complementary to direct searches for BSM particles. Recent measurements of the Higgs boson width using H->ZZ decays and of the invisible Higgs boson branching ratio have been performed at CMS with the full run 2 data set.

Stringent constraints on the invisible Higgs branching ratio are obtained, and evidence for offshell production of the Higgs boson is presented. The H->ZZ events are also used to set limits on anomalous couplings to vector bosons. These limits are compared with constraints on anomalous couplings obtained in a recent analysis of Higgs boson production in vector boson or gluon fusion, with Higgs boson decays into two tau leptons.
