New Physics Hints from Flavour
Valerio Gherardi
This Thesis presents my personal contributions to two distinct fields, namely the recent experimental anomalies in B-meson decays, and the longstanding quest for a theoretical expl…
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…
Low-energy phenomenology of scalar leptoquarks at one-loop accuracy
Valerio Gherardi, David Marzocca, Elena Venturini
We perform a complete study of the low-energy phenomenology of and lepto-quarks, aimed at addressing the observed deviations in -meson decays and the muon magnetic d…
Solving the Bethe-Salpeter Equation in Minkowski Space for a Fermion-Scalar system
J. H. Alvarenga Nogueira, D. Colasante, V. Gherardi +3
The ladder Bethe-Salpeter Equation of a bound (1/2)+ system, composed by a fermion and a scalar boson, is solved in Minkowski space, for the first time. The formal tools are the sa…
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…
