Higgs Precision (Higgcision) Era begins

Abstract

After the discovery of the Higgs boson at the LHC, it is natural to start the research program on the precision study of the Higgs-boson couplings to various standard model (SM) particles. We provide a generic framework for the deviations of the couplings from their SM values by introducing a number of parameters. We show that a large number of models beyond the SM can be covered, including two-Higgs-doublet models, supersymmetric models, little-Higgs models, extended Higgs sectors with singlets, and fourth generation models. We perform global fits to the most updated data from CMS, ATLAS, and Tevatron under various initial conditions of the parameter set. In particular, we have made explicit comparisons between the fitting results BEFORE and AFTER the Moriond 2013 meetings. Highlights of the results include: (i) the nonstandard decay branching ratio of the Higgs boson is less than 22%; (ii) the most efficient way to achieve the best fit for the data before the Moriond update is to introduce additional particle contributions to the triangular-loop functions of Hγγand Hgg vertices; (iii) the 1σallowed range of the relative coupling of HVV is 1.01 +0.13 -0.14, which means that the electroweak-symmetry breaking contribution from the observed Higgs boson leaves only a small room for other Higgs bosons; (iv) the current data do not rule out pseudoscalar couplings nor pseudoscalar contributions to the Hγγand Hgg vertices; and (v) the SM Higgs boson provides the best fit to all the current Higgs data.

48 pages, including 7 tables and 11 figures; in this revision we have updated the analysis using the most updated Higgs data after Moriond 2013; because of the change in CMS diphoton data, the fits change dramatically; we show the fits BEFORE and AFTER the Moriond update; references added
