Modular Invariant Dynamics and Fermion Mass Hierarchies around
Ferruccio Feruglio, Valerio Gherardi, Andrea Romanino +1
We discuss fermion mass hierarchies within modular invariant flavour models. We analyse the neighbourhood of the self-dual point , where modular invariant theories possess a r…
Lepton Flavour Symmetries
Ferruccio Feruglio, Andrea Romanino
We provide a general classification of flavour symmetries according to their interplay with the proper Poincare' and gauge groups and to their linear or nonlinear action in field s…
Rank-One Flavor Violation and B-meson anomalies
Valerio Gherardi, David Marzocca, Marco Nardecchia +1
We assume that the quark-flavor coefficients matrix of the semileptonic operators addressing the neutral-current B-meson anomalies has rank-one, i.e. it can be described by a singl…
Can an unbroken flavour symmetry provide an approximate description of lepton masses and mixing?
Y. Reyimuaji, A. Romanino
We provide a complete answer to the following question: what are the flavour groups and representations providing, in the symmetric limit, an approximate description of lepton mass…
Stable lepton mass matrices
Valerie Domcke, Andrea Romanino
We study natural lepton mass matrices, obtained assuming the stability of physical flavour observables with respect to the variations of individual matrix elements. We identify all…
A closer look to the sgoldstino interpretation of the diphoton excess
P. Baratella, J. Elias-Miro, J. Penedo +1
We revisit the sgoldstino interpretation of the diphoton excess in the context of gauge mediation. While the bound on the gluino mass might seem to make the sgoldstino contribution…
