1202.3697 (J. R. Espinosa et al.)

Fingerprinting Higgs Suspects at the LHC    [PDF]

J. R. Espinosa, Christophe Grojean, M. Muhlleitner, Michael Trott
We outline a method for characterizing deviations from the properties of a
Standard Model (SM) Higgs boson. We apply it to current data in order to
characterize up to which degree the SM Higgs boson interpretation is consistent
with experiment. We find that the SM Higgs boson is consistent with the current
data set at the 82 % confidence level, based on data of excess events reported
by CMS and ATLAS, which are interpreted to be related to the mass scale mh =
124-126 GeV and on published CL_s exclusion regions. We perform a global fit in
terms of two parameters characterizing the deviation from the SM value in the
gauge and fermion couplings of a Higgs. We find two degenerate minima in the
global fit and identify observables that can remove this degeneracy.
