Flavor Hierarchies the Right Way
Pavel Fileviez Perez, Clara Murgui
We propose a framework for fermion mass generation based on a universal seesaw. The Standard Model is extended by an Abelian gauge symmetry acting on right-handed fermions, togethe…
A Pati-Salam realization of the Nelson-Barr mechanism
Clara Murgui
We present a UV completion of the Standard Model in which quarks and leptons are unified under color SU(4). A single fermionic representation, the real antisymmetric, provides the…
Fluctuations in atom interferometers as a new tool for dark matter
Clara Murgui, Ryan Plestid
We propose the use of the super-binomial variance in the count rate of an atom interferometer as a novel signature of dark matter. We show that the dark matter induced shift in thi…
Coherently enhanced decoherence and cloud substructure of atom interferometers
Clara Murgui, Ryan Plestid
We study how coherent scattering of a background gas off an atom (or other matter) interferometer can lead to enhanced signals from phase shifts and contrast loss. We focus on the…
Leptogenesis in automatic Nelson-Barr models
Clara Murgui, Samuel Patrone
In this study, we numerically show that automatic Nelson-Barr models with new chiral fermions can simultaneously solve the strong CP problem and generate the observed baryon asymme…
