The measurement of the Higgs self-coupling at the LHC: theoretical status
J. Baglio, A. Djouadi, R. Grober +3
Now that the Higgs boson has been observed by the ATLAS and CMS experiments at the LHC, the next important step would be to measure accurately its properties to establish the detai…
Implications of LHC Higgs and SUSY searches for MSSM
F. Mahmoudi, A. Arbey, M. Battaglia +1
The implications of the LHC SUSY searches as well as the discovery of a new bosonic state compatible with the lightest Higgs boson will be discussed in the context of constrained a…
An update of the constraints on the phenomenological MSSM from the new LHC Higgs results
A. Arbey, M. Battaglia, A. Djouadi +1
Updated results on the search of Higgs bosons at the LHC with up to 17/fb of data have just been presented by the ATLAS and CMS collaborations. New constraints are provided by the…
The apparent excess in the Higgs to di-photon rate at the LHC: New Physics or QCD uncertainties?
J. Baglio, A. Djouadi, R. M. Godbole
The Higgs boson with a mass GeV has been observed by the ATLAS and CMS experiments at the LHC and a total significance of about five standard deviations has been…
Precision Higgs coupling measurements at the LHC through ratios of production cross sections
Abdelhak Djouadi
Now that the Higgs particle has been observed by the ATLAS and CMS experiments at the LHC, the next endeavour would be to probe its fundamental properties and to measure its coupli…
The Higgs sector of the phenomenological MSSM in the light of the Higgs boson discovery
Alexandre Arbey, Marco Battaglia, Abdelhak Djouadi +1
The long awaited discovery of a new light scalar at the LHC opens up a new era of studies of the Higgs sector in the SM and its extensions. In this paper we discuss the consequence…
The top quark and Higgs boson masses and the stability of the electroweak vacuum
S. Alekhin, A. Djouadi, S. Moch
The ATLAS and CMS experiments observed a particle at the LHC with a mass GeV, which is compatible with the Higgs boson of the Standard Model. A crucial question is, i…
Direct detection of Higgs-portal dark matter at the LHC
Abdelhak Djouadi, Adam Falkowski, Yann Mambrini +1
We consider the process in which a Higgs particle is produced in association with jets and show that monojet searches at the LHC already provide interesting constraints on the invi…
Les Houches 2011: Physics at TeV Colliders New Physics Working Group Report
G. Brooijmans, B. Gripaios, F. Moortgat +141
We present the activities of the "New Physics" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 30 May-17 June, 2011). Our report includes new agreem…
Sealing the fate of a fourth generation of fermions
Abdelhak Djouadi, Alexander Lenz
The search for the effects of heavy fermions in the extension of the Standard Model with a fourth generation is part of the experimental program of the Tevatron and LHC experiments…
Higgs Physics: Theory
Abdelhak Djouadi
I review the theoretical aspects of the physics of Higgs bosons, focusing on the elements that are relevant for the production and detection at present hadron colliders. After brie…
Implications of a 125 GeV Higgs for supersymmetric models
A. Arbey, M. Battaglia, A. Djouadi +2
Preliminary results of the search for a Standard Model like Higgs boson at the LHC with 5 fb-1 data have just been presented by the ATLAS and CMS collaborations and an excess of ev…
