Lunch seminar Alberto Mariotti
|When:||Th 17-12-2015 12:30 - 13:30|
Vrije Universiteit Brussel, Brussels, Belgium
I will review the current status of the supersymmetric extension of the Standard Model after the first run of LHC. In particular I will discuss the direct bounds from collider searches and also the implication for supersymmetric models descending from the BEH boson discovery. I will also review the usual paradigms for mediation of supersymmetry breaking. Then I will introduce scenarios with multiple supersymmetry breaking sectors in gauge mediation, characterised by the presence in the low energy spectrum of extra light fermionic degrees of freedom, the pseudo-goldstini. I will show how a simplified model in the MSSM with pseudo-goldstini can accommodate the 3-sigma Z-peaked excess recently reported by the ATLAS collaboration, without conflicting with other existing LHC searches.
