Abstract
In the standard model SM lepton flavor violating LFV Higgs decay is absent at renormalizable level and thus it is a good probe to new physics In this article we study a type of new physics that could lead to large LFV Higgs decay ie a leptonflavored dark matter DM model which is specified by a Majorana DM and scalar lepton mediators Different from other similar models with similar setup we introduce both lefthanded and righthanded scalar leptons They allow large LFV Higgs decay and thus may explain the tentative Brh → τμ ∼ 1 experimental results from the LHC In particular we find that the stringent bound from τ → μγ can be naturally evaded One reason among others is a large chirality violation in the mediator sector Aspects of relic density and especially radiative direct detection of the leptonic DM are also investigated stressing the difference from previous leptonflavored DM modelsThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
