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

A search for the Standard Model Higgs boson decaying to a pair of muons is presented. The focus of this analysis is on Higgs production in association with W and Z bosons. The full Run 2 data collected at the CMS experiment from 2016-2018 at a center of mass energy of √s=13 TeV are used. Events with at least two oppositely charged muons as well as at least one additional lepton, supposedly originating from the gauge boson, are selected. This selection reduces the dominant Drell Yan background events as they do not contain a prompt third lepton. Because of the low signal yields in these Higgs decay channels, it is important to achieve a high signal efficiency while suppressing background contributions. Studies to this end are presented, including final state radiation photon recovery and multivariate prompt lepton identification.
