Abstract: The newly discovered Higgs-like particle may have modified interactions with the Standard Model particles. Naively, the strength of these interactions may be extracted from rate measurements at the LHC. However, Higgs decays into new light particles may dramatically affect the rates so that the extraction of the Higgs couplings is possible only under some theoretical assumptions. I will present a method for determining the Higgs couplings and total width based on the existing data and a well-motivated theoretical constraint.
