The properties of the observed Higgs boson with mass around 125 GeV are constrained by a wealth of experimental results targeting different combinations for the production and deca…
Dilepton constraints in the Inert Doublet Model from Run 1 of the LHC
G. Belanger, B. Dumont, A. Goudelis +3
Searches in final states with two leptons plus missing transverse energy, targeting supersymmetric particles or invisible decays of the Higgs boson, were performed during Run 1 of…
Lilith: a tool for constraining new physics from Higgs measurements
Jeremy Bernon, Beranger Dumont
The properties of the observed Higgs boson with mass around 125 GeV can be affected in a variety of ways by new physics beyond the Standard Model (SM). The wealth of experimental r…
Higgs, supersymmetry and dark matter after Run I of the LHC
Beranger Dumont
Two major problems call for an extension of the Standard Model (SM): the hierarchy problem in the Higgs sector and the dark matter in the Universe. The discovery of a Higgs boson w…
New features of MadAnalysis 5 for analysis design and reinterpretation
Eric Conte, Béranger Dumont, Benjamin Fuks +1
We present MadAnalysis 5, an analysis package dedicated to phenomenological studies of simulated collisions occurring in high-energy physics experiments. Within this framework, use…
Implementation and validation of the LHC SUSY searches with MadAnalysis 5
Beranger Dumont
Separate, validated implementations of the ATLAS and CMS new physics analyses are necessary to fully exploit the potential of these searches. To this end, we use MadAnalysis 5, a p…
Addendum to "Constraints on and future prospects for Two-Higgs-Doublet Models in light of the LHC Higgs signal"
Beranger Dumont, John F. Gunion, Yun Jiang +1
We update the constraints on Two-Higgs-Doublet Models of Type I and II discussed in arXiv:1405.3584 using the latest LHC measurements of the ~125.5 GeV Higgs signal as of Summer 20…
Status of Higgs couplings after Run-1 of the LHC using Lilith 1.0
Jeremy Bernon, Beranger Dumont, Sabine Kraml
We provide an update of the global fits of the couplings of the 125.5 GeV Higgs boson using all publicly available experimental results from Run-1 of the LHC as per Summer 2014. Th…
Towards a public analysis database for LHC new physics searches using MadAnalysis 5
B. Dumont, B. Fuks, S. Kraml +6
We present the implementation, in the MadAnalysis 5 framework, of several ATLAS and CMS searches for supersymmetry in data recorded during the first run of the LHC. We provide exte…
Higgs coupling measurements and impact on the MSSM
Beranger Dumont
Run I of the LHC has not revealed any sign of new physics beyond the Standard Model (BSM). However, the discovery of an SM-like Higgs boson with mass around 125 GeV opens up new po…
