Abstract: A search for soft unclustered energy patterns (SUEPs) produced in association with a W boson is presented. The analysis is based on proton-proton collision data corresponding to an integrated luminosity of 138 fb$ ^{-1} $, collected between 2016 and 2018 with the CMS detector at $ \sqrt{s}= $ 13 TeV. Final states containing a W boson candidate and a high multiplicity of soft tracks are explored for the first time. Upper limits are set on the branching fraction for the Higgs boson decay to a SUEP.
