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…
Extra U(1) as natural source of a monochromatic gamma ray line
Emilian Dudas, Yann Mambrini, Stefan Pokorski +1
Extensions of the Standard Model with an extra U'(1) abelian group generically generate terms coming from loops of heavy fermions, leading to three gauge boson couplings, in partic…
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…
The MSSM Higgs Sector with a Dynamical Goldstino Supermultiplet
Christoffer Petersson, Alberto Romagnoni
We consider a supersymmetric realization of the MSSM Higgs sector, where the soft terms are promoted to supersymmetric operators and a minimal weakly coupled hidden sector is inclu…
