Description
abstract:
The observed pattern of mixing in the neutrino sector may be explained by the
presence of a non-Abelian, discrete flavour symmetry broken into residual
subgroups at low energies. These flavour models require the presence of
Standard Model singlet scalars, namely flavons, which can promptly decay to charged leptons
in a flavour-conserving or violating manner. In this talk, I will present the constraints on
the model parameters of an A4 leptonic flavour model using a synergy of
g-2, charged lepton flavour conversion and collider data. The
most powerful constraints derive from the MEG collaboration's result on
mu to e gamma and the reinterpretation of an 8 TeV ATLAS search for
anomalous productions of multi-leptonic final states.
