One notoriously difficult problem in perturbative gauge mediation of supersymmetry breaking via messenger fields is the generic presence of a phenomenologically unacceptable vacuum with messenger vevs, with a lower energy than the desired (MSSM) vacuum. We investigate the possibility that quantum corrections promote the latter to the ground state of the theory, and find that this is indeed...

The fate of R-parity is one of the central issues in the minimal supersymmetric standard model. Gauged $B-L$ symmetry provides a natural framework for addressing this question. I will study the theory and phenomenology in a class of models where gauged R-parity is spontaneously broken at TeV, including the predictions of neutrino masses and the signature for such theories to be detected at the LHC.

I discuss the potential of measuring CP violation in three body decays, paying particular attention to the different possible origins of the "strong" CP-even phase. This phase can be obtained from the propagation of intermediate state particles - either when diagrams with different intermediate particles interfer, or when the intermediate state is off-shell by a different amount. I will...

We investigate the influence of the boundary conditions of minimal
supergravity (mSUGRA) on the supersymmetric mechanism for lepton
flavour violation (LFV) proposed recently [1], within the
framework of the MSSM extended by TeV-scale singlet heavy neutrinos.
We find that the consideration of the mSUGRA boundary condition may
increase the branching ratios of ...
