Higgs couplings and BSM physics: Run I Legacy constraints

Abstract : We consider the Higgs boson decay processes and its production including all Run I results, through a parametrisation tailored for testing models of new physics beyond the Standard Model, and complementary to the one used by the LHC working groups. Different formalisms allow to best address different aspects of the Higgs boson physics. The choice of a particular parametrisation depends on a non-obvious balance of quantity and quality of the available experimental data, envisaged purpose for the parametrisation and degree of model independence, importance of the radiative corrections, and scale at which new particles appear explicitly in the physical spectrum. The most refined constraints can only be obtained by the experimental collaborations at present, as information about correlation between the various uncertainties on the different decay modes is not completely available in the public domain. It is therefore important that different approaches are considered and that the most detailed information is made available to allow testing the different aspects of the Higgs boson physics and the possible hints of physics beyond the Standard Model.
