Mutau symmetry and the Littlest Seesaw
/ King, Stephen F. ; Nishi, Celso C.
Motivated by the latest neutrino oscillation data which is consistent with maximal atmospheric mixing and maximal leptonic CP violation, we review various results in μτ symmetry, then include several new observations and clarifications, including identifying a new general form of neutrino mass matrix with μτ symmetry.

$SO\left(10\right)$ inspired ${Z}^{\prime}$ models at the LHC
/ King, Simon J. D. ; King, Stephen F. ; Moretti, Stefano
We study and compare various ${Z}^{\prime}$ models arising from $SO\left(10\right)$, focusing in particular on the Abelian subgroup $U(1{)}_{R}\times U(1{)}_{BL}$, broken at the TeV scale to Standard Model hypercharge $U(1{)}_{Y}$. [...]

Nonuniversal Z ′ from fluxed GUTs
/ Crispim Romao, Miguel ; King, Stephen F. ; Leontaris, George K.
We make a first systematic study of nonuniversal TeV scale neutral gauge bosons Z′ arising naturally from a class of Ftheory inspired models broken via SU(5) by flux. [...]

Comprehensive renormalization group analysis of the littlest seesaw model
/ Geib, Tanja ; King, Stephen F.
We present a comprehensive renormalization group analysis of the littlest seesaw model involving two righthanded neutrinos and a very constrained Dirac neutrino Yukawa coupling matrix. [...]

Accidental Peccei–Quinn symmetry from discrete flavour symmetry and Pati–Salam
/ Björkeroth, Fredrik ; Chun, Eung Jin ; King, Stephen F.
We show how an accidental U(1) Peccei–Quinn (PQ) symmetry can arise from a discrete A4 family symmetry combined with a discrete flavour symmetry Z3×Z52 , in a realistic Pati–Salam unified theory of flavour. [...]

Minima of multiHiggs potentials with triplets of Δ(3 n 2 ) and Δ(6 n 2 )
/ de Medeiros Varzielas, Ivo ; King, Stephen F. ; Luhn, Christoph ; Neder, Thomas
We analyse the minima of scalar potentials for multiHiggs models where the scalars are arranged as either one triplet or two triplets of the discrete symmetries A4 , S4 , Δ(27) , Δ(54) , as well as Δ(3n2) and Δ(6n2) with n>3 . [...]

Golden Littlest Seesaw
/ Ding, GuiJun ; King, Stephen F. ; Li, CaiChang
We propose and analyse a new class of Littlest Seesaw models, with two righthanded neutrinos in their diagonal mass basis, based on preserving the first column of the Golden Ratio mixing matrix. [...]

Leptogenesis after chaotic sneutrino inflation and the supersymmetry breaking scale
/ Björkeroth, Fredrik ; King, Stephen F. ; Schmitz, Kai ; Yanagida, Tsutomu T.
We discuss resonant leptogenesis arising from the decays of two nearlydegenerate righthanded neutrinos, identified as the inflaton and stabiliser superfields in a model of chaotic sneutrino inflation. [...]

750 GeV diphoton excess from E 6 in Ftheory GUTs
/ Karozas, Athanasios ; King, Stephen F. ; Leontaris, George K. ; Meadowcroft, Andrew K.
We interpret the 750–760 GeV diphoton resonance as one or more of the spinless components of a singlet superfield arising from the three 27dimensional representations of E6 in Ftheory, which also contain three copies of colourtriplet charge ∓1/3 vectorlike fermions Di,D¯i and inert Higgs doublets to which the singlets may couple.

Neutrino mass and mixing in the seesaw playground
/ King, Stephen F.
We discuss neutrino mass and mixing in the framework of the classic seesaw mechanism, involving righthanded neutrinos with large Majorana masses, which provides an appealing way to understand the smallness of neutrino masses. [...]
