Gauge-flavon unification
Alfredo Aranda, Francisco J. de Anda, Stephen F. King
In this paper we propose the idea that flavons can emerge from extra dimensional gauge fields, referred to as gauge-flavon unification (GFU) analogous to gauge-Higgs unification (G…
Is it possible to explain the muon and electron in a model?
A. E. Cárcamo Hernández, S. F. King, H. Lee +1
In order to address this question, we consider a simple renormalisable and gauge invariant model in which the only has couplings to the electron and muon and their associated…
Flavon alignments from orbifolding: model with
Francisco J. de Anda, Stephen F. King, Elena Perdomo +1
We systematically develop the formalism necessary for ensuring that boundary conditions of flavon fields in extra dimensions are consistent with heterotic string theory. Having dev…
Modular and Symmetries and Their Fixed Points: New Predictive Examples of Lepton Mixing
Gui-Jun Ding, Stephen F. King, Xiang-Gan Liu +1
In the modular symmetry approach to neutrino models, the flavour symmetry emerges as a finite subgroup of the modular symmetry, broken by the vacuum expectation value (VEV) o…
Trimaximal TM mixing with two modular groups
Stephen F. King, Ye-Ling Zhou
We discuss a minimal flavour model with twin modular symmetries, leading to trimaximal TM lepton mixing in which the first column of the tri-bimaximal lepton mixing matrix is p…
Modular Symmetry Models of Neutrinos and Charged Leptons
Gui-Jun Ding, Stephen F. King, Xiang-Gan Liu
We present a comprehensive analysis of neutrino mass and lepton mixing in theories with modular symmetry, where the only flavon field is the single modulus field , and all…
A New Littlest Seesaw Model
Ping-Tao Chen, Gui-Jun Ding, Stephen F. King +1
We propose and discuss a new Littlest Seesaw model, realised in the tri-direct CP approach, in which the couplings of the two right-handed neutrinos to the lepton doublets are prop…
Multiple modular symmetries as the origin of flavour
Ivo de Medeiros Varzielas, Stephen F. King, Ye-Ling Zhou
We develop a general formalism for multiple moduli and their associated modular symmetries. We apply this formalism to an example based on three moduli with finite modular symmetri…
Non-Minimal Flavour Violation in SUSY GUTs
Samuel J. Rowley, Jordan Bernigaud, Björn Herrmann +1
We study CP-conserving non-minimal flavour violation in inspired Supersymmetric Grand Unified Theories (GUTs), focussing on the regions of parameter space where…
Theory Review of Neutrino Models and CP Violation
Stephen F King
Although the measurement of the reactor angle has killed tribimaximal lepton mixing, its descendants survive with charged lepton corrections, or in less constrained forms such as t…
Neutrino Mass and Mixing with Modular Symmetry
Gui-Jun Ding, Stephen F. King, Xiang-Gan Liu
We present a comprehensive analysis of neutrino mass and lepton mixing in theories with modular symmetry. We construct the weight 2, weight 4 and weight 6 modular forms of le…
New Weinberg operator for neutrino mass and its seesaw origin
Josu Hernandez-Garcia, Stephen F. King
We consider a new Weinberg operator for neutrino mass of the form involving two different Higgs doublets with opposite hypercharge, where $\tilde{…
Origin of Yukawa couplings for Higgs and leptoquarks
Ivo de Medeiros Varzielas, Stephen F. King
We propose a model in which the Yukawa couplings of Higgs doublets are related to the couplings of the chiral fermions to a scalar leptoquark triplet. This is due to their common o…
Unification, Proton Decay and Topological Defects in non-SUSY GUTs with Thresholds
Joydeep Chakrabortty, Stephen F. King, Rinku Maji
We calculate the proton lifetime and discuss topological defects in a wide class of non-supersymmetric (non-SUSY) and Grand Unified Theories (GUTs), broken via left…
Littlest mu-tau seesaw
Stephen F. King, Ye-Ling Zhou
We propose a reflection symmetric Littlest Seesaw (-LSS) model. In this model the two mass parameters of the LSS model are fixed to be in a special ratio by symmetry, so…
