Exploring a supersymmetric four-Higgs doublet model — •Lucas Willanzheimer1, Franziska Lohner1, and Gudrid Moortgat-Pick1,2 — 1Universität Hamburg — 2Deutsches Elektronen-Synchrotron DESY
Motivated by recent results from the ATLAS and CMS collaborations which reveal excesses in studies of decays into top quark pairs t t and tau leptons τ+ τ− at approximately 400 GeV -phenomena that the minimal supersymmetric standard model (MSSM) cannot explain simultaneously- we explore, in this study, the Higgs sector of a supersymmetric four-Higgs doublet model. Assuming a symmetry in which each type of matter, including up-type- and down-type-quarks as well as charged leptons, couples exclusively to its ’own’ doublet, our aim is to investigate whether such a supersymmetry-type model, with its Yukawa-sector, could embed excesses of such kind.
