If the Higgs boson were the only particle within the LHC accessible range, precision measurement of the Higgs's properties would play a unique role in studying electroweak symmetry breaking as well as possible new physics. We try to use low energy experiments such as rare B decay to constrain a challenging decay mode of Higgs, in which a Higgs decays to a pair of light (≈ 1 ∼ 2 GeV) SM singlet S and becomes invisible. By using the current experimental bound of rare decay B→ Kνν̅ and computingdoi:10.1103/physrevd.81.054004 fatcat:gh5g76mghva65ovgp5hnvie4qu
