The Fermilab Muon g-2 experiment, E989, is presently being constructed and is seeking to measure the anomalous magnetic moment of the muon to a precision of 0.14ppm: a factor of four better than the previous Brookhaven measurement which has a long-standing discrepancy with respect to the SM prediction of approximately 3.5 standard deviations. I will review the status of the Fermilab experiment...

I discuss a scenario for leptons with a flavor and a CP symmetry. If these symmetries are broken in a particular way, lepton mixing angles as well as the Dirac and the Majorana phases can be predicted in terms of quantities determined by the
symmetries of the theory and only one continuous parameter. I present results for a large class of flavor and CP symmetries. Furthermore, I study...

I present extensions of the Standard Model, where the global symmetries baryon and lepton number are gauged and subsequently spontaneously broken. These theories are consistent with collider bounds and cosmology, and have intriguing consequences due to the requirement of anomaly cancellation: lepto-baryon fields that have to be introduced can be a dark matter candidate and/or generate neutrino...

The use of discrete symmetries to explain fermion masses and mixings has been a popular and profitable tool in particle physics. Some of the most interesting features shown in both the quark and lepton sectors, specially with regards to their mixing patterns, strongly hint at the presence of some underlying "flavor" symmetry. On the other hand, the puzzling wide spread in the mass spectrum of...

An important class of flavour groups that are subgroups of U(3) and that predict experimentally viable lepton mixing parameters including Majorana phases, is the Delta(6n^2) series. The most well-known member is Delta(24)=S_4. I present results of several extensive studies of lepton mixing predictions obtained in models with a Delta(6n^2) flavour group that preserve either the full Klein...
