Muon g-2 and Neutrino Mass in a New Minimal Extension of the MSSM

Abstract

If the one term $({\hat{\nu }}_e\hat{\mu }-\hat{e}{\hat{\nu }}_{\mu }){\hat{\tau }}^c$ is added to the MSSM (Minimal Supersymmetric Standard Model) superpotential, the recently observed muon g--2 (anomalous magnetic moment) excess can be explained very simply by a light ${\tilde{\nu }}_e$. If the soft symmetry-breaking terms ${\hat{\nu }}_{\alpha }{\hat{h}}_2^0-{\hat{l}}_{\alpha }{\hat{h}}_2^{+}$ are also added, realistic neutrino masses (with bimaximal mixing) are generated as well.
