Supersymmetry confronts Bs -> mu+mu-: Present and future status
A. Arbey, M. Battaglia, F. Mahmoudi +1
The purely leptonic rare decay Bs -> mu+mu- is very sensitive to supersymmetric contributions which are free from the helicity suppression of its Standard Model diagrams. The recen…
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…
Dark Matter in a twisted bottle
Alexandre Arbey, Giacomo Cacciapaglia, Aldo Deandrea +1
The real projective plane is a compact, non-orientable orbifold of Euler characteristic 1 without boundaries, which can be described as a twisted Klein bottle. We shortly review th…
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…
Light Neutralino Dark Matter in the pMSSM: Implications of LEP, LHC and Dark Matter Searches on SUSY Particle Spectra
A. Arbey, M. Battaglia, F. Mahmoudi
We investigate the viability of light neutralino scenarios as promoted by dark matter direct detection experiments. Using high statistics scans in the pMSSM we have identified seve…
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…
