Search for a SM Higgs boson decaying to a pair of muons in associated production with a gauge boson — •Tobias Kramer, Torben Lange, Oliver Rieger, and Peter Schleper — Universität Hamburg

Studies on developing a search for Higgs decays into muons in VH associated production are presented. The full Run 2 data collected at the CMS experiment from 2016-2018 at a center of mass energy of 13 TeV are used. Events with at least two oppositely charged muons as well as at least one additional lepton, identified as originating from the gauge boson, are selected. These requirements efficiently select signal events and reduce the initially dominant Drell-Yan background events, which typically do not contain a prompt third lepton. The search strategy, including multivariate prompt lepton identification, BDT optimization, and categorization is presented. Estimates of the sensitivity, derived using a data driven background estimation, are given.
