Flavor hierarchies with nonminimal irreducible representations
Hannah Banks, Graeme Crawford, Matthew McCullough +1
We propose a new class of flavour models in which the spurion which breaks Standard Model flavour symmetries transforms in a non-minimal representation. Hierarchies in fermion mass…

A Nuclear Interferometer for Ultra-Light Dark Matter Detection
Hannah Banks, Elina Fuchs, Matthew McCullough
We propose the nuclear interferometer - a single-photon interferometry experiment based upon the thorium-229 nuclear clock transition - as a novel detector for ultra-light dark mat…

New Physics at Tera-: Precision Renormalised
Lukas Allwicher, Matthew McCullough, Sophie Renner
We study the power of a Tera- run at FCC-ee for indirectly detecting or constraining heavy new physics. Our main finding is that nearly every new particle which matches at tree…
