Higgs diphoton rate enhancement from supersymmetric physics beyond the MSSM
Marcus Berg, Igor Buchberger, D. M. Ghilencea +1
We show that supersymmetric "new physics" beyond the MSSM can naturally accommodate a Higgs mass near 126 GeV and enhance the signal rate in the Higgs to diphoton channel, while th…
Field Theory Interpretation of N=2 Stringy Instantons
Riccardo Argurio, Davide Forcella, Alberto Mariotti +2
We consider stringy instanton contributions to the prepotential of low-energy N=2 theories engineered by D-brane set ups at orbifold and orientifold singularities. We show that suc…
Low Scale Supersymmetry Breaking and its LHC Signatures
Emilian Dudas, Christoffer Petersson, Pantelis Tziveloglou
We study the most general extension of the MSSM Lagrangian that includes scenarios in which supersymmetry is spontaneously broken at a low scale f. The spurion that parametrizes su…
Liberating Higgs couplings in supersymmetry
Christoffer Petersson, Alberto Romagnoni, Riccardo Torre
In the MSSM, the Higgs couplings to down-type quarks and leptons, normalized with respect to their corresponding Standard Model values, coincide at tree-level and this degeneracy i…
Photophilic Higgs from sgoldstino mixing
Brando Bellazzini, Christoffer Petersson, Riccardo Torre
The spontaneous breaking of linearly realized N=1 supersymmetry implies the existence of a pseudo-Goldstone fermion, the goldstino, and of its complex scalar superpartner, the sgol…
Higgs decay with monophoton + MET signature from low scale supersymmetry breaking
Christoffer Petersson, Alberto Romagnoni, Riccardo Torre
We study the decay of a standard model-like Higgs boson into a gravitino and a neutralino, which subsequently decays promptly into another gravitino and a photon. Such a decay can…
