Pati-Salam models with A4 modular symmetry

Journal of High Energy Physics
The flavor structure of quarks and leptons and quark-lepton unification are studied in the framework of Pati-Salam models with A 4 modular symmetry. The three generations of the left-handed and right-handed fermions are assigned to be triplet or singlets

Universal predictions of Siegel modular invariant theories near the fixed points

Journal of High Energy Physics
We analyze a general class of locally supersymmetric, CP and modular invariant models of lepton masses depending on two complex moduli taking values in the vicinity of a fixed point, where the theory enjoys a residual symmetry under a finite group.

Comprehensive Bayesian exploration of Froggatt-Nielsen mechanism

Journal of High Energy Physics
The Froggatt-Nielsen (FN) mechanism successfully explains the hierarchical structure of fermion Yukawa couplings by introducing a U(1) flavor symmetry with distinct charge assignments for different fermion generations.

Modular flavor models with positive modular weights: a new lepton model building

Journal of High Energy Physics
We propose an interesting assignment of positive modular weights for fields in a modular non-Abelian discrete flavor symmetry. By this assignment, we can construct inverse seesaw and linear seesaw models without any additional symmetries which possess ...

Heavy flavour in high-energy nuclear collisions: theory overview of transport calculations

, 2018
Transport calculations are the tool to study medium modifications of heavy-flavour particle distributions in high-energy nuclear collisions. We give a brief overview on their state-of-the art, on the information one can extract, on the questions remaining open and on further analysis to carry out in the near future.

Theories of flavour from the Planck scale to the electroweak scale

The flavour puzzle remains as one of the most intriguing enigmas of particle physics. In this thesis, we propose and study theories of flavour which generically hint to a multi-scale origin of flavour. First we explore the idea of fermiophobic models and messenger dominance, where the chiral fermions of the Standard Model are uncharged under (part of ...

The Nature of Massive Neutrinos and Unified Theories of Flavour

, 2013
The present Ph.D. thesis is devoted to two fundamental unsolved problems of neutrino physics, which are intimately connected: determining the nature - Dirac or Majorana - of massive neutrinos, which is related with the possibility of existence of New Physics beyond that predicted by the Standard Model (SM) of particle interactions, and, discovering the
