The Minimal High-Quality QCD Axion
Mario Fernández Navarro
The canonical QCD axion is minimal but not high quality. We identify a minimal high-quality QCD axion, in which the Peccei-Quinn symmetry emerges as a gauge-origin boundary remnant…
The structure of multi-axion solutions to the strong CP problem
Mario Fernández Navarro, Marta F. Zamoro, Marko Pesut +1
A broad experimental program is targeting the QCD axion band predicted by single-axion solutions to the strong CP problem. Multi-axion theories provide a well-motivated departure f…
A Limit on the Total Lepton Number in the Universe from BBN and the CMB
Valerie Domcke, Miguel Escudero, Mario Fernandez Navarro +1
At temperatures below the QCD phase transition, any substantial lepton number in the Universe can only be present within the neutrino sector. In this work, we systematically explor…
Lepton Flavor Asymmetries: from the early Universe to BBN
Valerie Domcke, Miguel Escudero, Mario Fernandez Navarro +1
Large primordial lepton flavor asymmetries with almost vanishing total baryon-minus-lepton number can evade the usual BBN and CMB constraints if neutrino oscillations lead to perfe…
Theories of flavour from the Planck scale to the electroweak scale
Mario Fernández Navarro
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-sca…
Tri-unification: a separate for each fermion family
Mario Fernández Navarro, Stephen F. King, Avelino Vicente
In this paper we discuss with cyclic symmetry as a possible grand unified theory (GUT). The basic idea of such a tri-unification is that there is a separate for…
Twin Pati-Salam theory of flavour for a new picture of -anomalies
Mario Fernández Navarro
We discuss a theory of flavour which can simultaneously explain and connect the origin of the Standard Model flavour hierarchies with the $U_{1}(\mathbf{3},\mathrm{\mathbf{1},2/3})…
Tri-hypercharge: a separate gauged weak hypercharge for each fermion family as the origin of flavour
Mario Fernández Navarro, Stephen F. King
We propose a tri-hypercharge (TH) embedding of the Standard Model (SM) in which a separate gauged weak hypercharge is associated with each fermion family. In this way, every quark…
Flavour hierarchies and -anomalies in a twin Pati-Salam theory of flavour
Mario Fernández Navarro
In this manuscript, based on arXiv:2209.00276, I present a model which can simultaneously explain and connect the flavour hierarchies of the Standard Model with flavour anomalies i…
-anomalies in a twin Pati-Salam theory of flavour including the 2022 LHCb analysis
Mario Fernández Navarro, Stephen F. King
We perform a comprehensive phenomenological analysis of the twin Pati-Salam theory of flavour, focussing on the parameter space relevant for interpreting the -anomalies via vect…
Fermiophobic model for simultaneously explaining the muon anomalies and
Mario Fernández Navarro, Stephen F. King
We discuss a simple renormalisable, gauge invariant model with a fermiophobic boson: it has no couplings to the three Standard Model (SM) chiral families, but does couple to a…
