DESCRIPTION:Speakers: zhaofeng kang (KIAS)\nIn the standard model (SM)\, H
 iggs lepton-flavor-violating (LFV) decay is absent and thus it is a good p
 robe to new physics. In this article we study a type of new physics that c
 ould lead to large Higgs LFV decay\, i.e.\, leptophlic dark matter (DM) sp
 ecified by the particle property of DM (a Majorana fermion) and DM-SM medi
 ators (scalar leptons). Different than other similar setups\, here we intr
 oduce both the left-handed and right-handed scalar leptons. They allow for
  large LFV in Higgs decay and thus may explain the tentative Br$(h\\ra\\ta
 u\\mu)\\sim1\\%$. In particular\, we find that the stringent bound from $\
 \tau\\ra\\mu\\gamma$ can be naturally avoided. Aspects of relic density an
 d especially radiative direct detection of the leptonic DM are also invest
 igated.\n\nhttps://indico.icrr.u-tokyo.ac.jp/event/23/contributions/837/
