Residual Symmetries and Scalar Multiplet Vacuum Alignment in Non-Abelian Flavour Models
Ivo de Medeiros Varzielas, Ming-Shau Liu, Amartya Sengupta +1
We demonstrate that, upon minimizing a renormalizable, single-scalar potential invariant under a non-Abelian symmetry, special orientations in the associated vacuum alignment of th…
Revisiting strong-coupling determinations from event shapes
Guido Bell, Christopher Lee, Yiannis Makris +2
We reassess the theoretical uncertainties of strong-coupling determinations from a global fit to the thrust data, focusing in particular on the scheme dependence associat…
Froggatt-Nielsen Meets the SMEFT
Eetu Loisa, Jim Talbert
We study the matching of Froggatt-Nielsen theories of flavour onto the Standard Model Effective Field Theory (SMEFT), upon integrating out a heavy Beyond-the-Standard-Model (BSM) s…
Effects of Renormalon Scheme and Perturbative Scale Choices on Determinations of the Strong Coupling from Event Shapes
Guido Bell, Christopher Lee, Yiannis Makris +2
We study the role of renormalon cancellation schemes and perturbative scale choices in extractions of the strong coupling constant and the leading non-perturbative shift…
No-go limitations on UV completions of the Neutrino Option
Ilaria Brivio, Jim Talbert, Michael Trott
We discuss the possible origin of the Majorana mass scale(s) required for the "Neutrino Option" where the electroweak scale is generated simultaneously with light neutrino masses i…
PeV Sterile Masses from D-Brane Instantons -- Motivating Stringy Neutrino Options?
Jim Talbert
We show that when sterile Majorana neutrino masses are generated non-perturbatively through instantonic interactions in certain classes of string compactifications (e.g. Type IIA o…
