Motivated by the absence, so far, of any signal for the coloured supersymmetric particles, we focus on the possibility that the electroweak sector may play the leading role in discovering supersymmetry. So far, the interest in the supersymmetric electroweak sector has often been linked to the fact that the LSP might account for the observed Dark Matter in the universe. The new LHC and...

I will discuss a simple and predictive model that combines the NMSSM and Gauge Mediation. Originally proposed by Delgado, Giudice and Slavich, we have re-analyzed this model and found new interesting regions in the parameter space with a light singlet state that mixes with the SM-like Higgs at 125 GeV. This mixing is small enough to evade LEP and LHC constraints, but large enough to give a...

The idea of naturalness, in its original version, refers only to the finite renormalisation of the Higgs boson mass induced by the introduction of heavier states. It is still a powerful heuristic principle in model building beyond the SM. A compelling case is provided by the generation of neutrino masses. The right-handed sector responsible for the seesaw mechanism is made supersymmetric to...

62. Lepton dipole moments in a SUSY low scale seesaw model

The results for anomalous dipole moment and electric dipole moment are presented in the MSSM extended by low scale heavy neutrinos. The analysis of possible contributions is presented, and found that the CP phase originates only for additional phase introduced in the model, leading to the electron EDM that can be observed in future experiments.
