SUMMARY:Search for new non-standard decay modes of SM-like Higgs at th
 e LHC\, Theory Seminar (High Energy/Cosmology)\, Jinrui Huang\, Univer
 sity of California\, Irvine
DESCRIPTION:We present strategies of searching for supersymmetric non-
 standard decays of Standard Model (SM)-like Higgs bosons (h2) at Large
  Hadron Collider (LHC)\, motivated by ''Dark Light Higgs'' (DLH) scena
 rio. The DLH sccenario represents a limit of the nearly-Peccei-Quinn-s
 ymmetric Next-to-Minimal Supersymmetric Standard Model\, where there n
 aturally co-exist two light singlet-like particles: a scalar (h1)\, a 
 pseudoscalar (a1)\, and a light singlino-like DM candidate (chi_1)\, a
 ll with masses of order 10 GeV or below. In this scenario\, the SM-lik
 e Higgs bosons typically decay dominantly into a pair of neutralinos\,
  allowing themselves to be as light as below 100 GeV. We systematicall
 y study the searches of both the SM-like and the light Higgs bosons at
  the LHC\, using the supersymmetric non-standard decay chain: h2 ->  c
 hi_1 chi_2\, chi_2 -> chi_1 (h1\, a1) with the h1 or a1 further decayi
 ng into a pair of fermions (including diMuon\, diTau and b bbar\, etc)
