The anomalous magnetic dipole moment of the muon can be both measured and computed to very high precision, making it a powerful probe to test the standard model and search for new physics such as SUSY. The previous measurement by the Brookhaven E821 experiment found a ~3 standard deviation discrepancy from the predicted value. The new g-2 experiment at Fermilab will improve the precision by a...

We investigate the scalar sector in an extension of the Minimal Supersymmetric Standard Model (MSSM) containing a SU(2) Higgs triplet of zero hypercharge and a gauge singlet. In particular, we focus on a scenario of this model which allows a light pseudoscalar, lighter than the discovered Higgs boson, consistent with the most recent data from the LHC and the earlier data from the LEP...
