Higgs Couplings at the End of 2012
G. Belanger, B. Dumont, U. Ellwanger +2
Performing a fit to all publicly available data, we analyze the extent to which the latest results from the LHC and Tevatron constrain the couplings of the Higgs boson-like state a…
Higgs Bosons at 98 and 125 GeV at LEP and the LHC
Geneviève Bélanger, Ulrich Ellwanger, John F. Gunion +3
We discuss NMSSM scenarios in which the lightest Higgs boson is consistent with the small LEP excess at about 98 GeV in with $h\to b\anti b$ and the heavier H…
PAMELA and FERMI-LAT limits on the neutralino-chargino mass degeneracy
Genevieve Belanger, Celine Boehm, Marco Cirelli +2
Searches for Dark Matter (DM) particles with indirect detection techniques have reached important milestones with the precise measurements of the anti-proton and gamma-ray spectra,…
Two Higgs Bosons at the Tevatron and the LHC?
G. Belanger, U. Ellwanger, J. F. Gunion +2
The best fit to the Tevatron results in the bb channel and the mild excesses at CMS in the gamma-gamma channel at 136 GeV and in the tau-tau channel above 132 GeV can be explained…
Testing Minimal Universal Extra Dimensions Using Higgs Boson Searches at the LHC
Genevieve Belanger, Alexander Belyaev, Matthew Brown +2
Large Hadron Collider (LHC) searches for the SM Higgs boson provide a powerful limit on models involving Universal Extra Dimensions (UED) where the Higgs production is enhanced. We…
Light neutralino dark matter in the MSSM and its implication for LHC searches for staus
Genevieve Belanger, Sanjoy Biswas, Celine Boehm +1
It was shown in a previous study that a lightest neutralino with mass below 30 GeV was severely constrained in the minimal supersymmetric standard model (MSSM), unless it annihilat…
Mixed sneutrino dark matter in light of the 2011 XENON and LHC results
Beranger Dumont, Genevieve Belanger, Sylvain Fichet +2
In the context of supersymmetric models in which small Dirac neutrino masses are generated by supersymmetry breaking, a mainly right-handed (RH) mixed sneutrino can be an excellent…
Model-Independent Bounds on Squarks from Monophoton Searches
Genevieve Belanger, Matti Heikinheimo, Veronica Sanz
Supersymmetry with a compressed spectrum could be responsible for the negative results from supersymmetric searches at LHC. Squarks and gluinos well below the TeV scale could have…
Searches for New Physics: Les Houches Recommendations for the Presentation of LHC Results
S. Kraml, B. C. Allanach, M. Mangano +30
We present a set of recommendations for the presentation of LHC results on searches for new physics, which are aimed at providing a more efficient flow of scientific information be…
The 125 GeV Higgs in the NMSSM in light of LHC results and astrophysics constraints
Daniel Albornoz Vasquez, Genevieve Belanger, Celine Boehm +3
Recent LHC data suggest an excess in the Higgs decay channels into gamma gamma, W W and Z Z at roughly 125 GeV. The current excess in the diphoton channel is twice that expected fr…
