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…
Coherent collisional decoherence
Leonardo Badurina, Clara Murgui, Ryan Plestid
We study the decoherence of a system of non-interacting heavy particles (atoms) due to coherent scattering with a background gas. We introduce a framework for computing the ind…
Finite Naturalness and Quark-Lepton Unification
Pavel Fileviez Perez, Clara Murgui, Samuel Patrone +2
We study the implications of finite naturalness in Pati-Salam models where is embedded in . For the minimal realization at low-scale of quark-lepton unification, w…
Contrast Loss from Astrophysical Backgrounds in Space-Based Matter-Wave Interferometers
Yufeng Du, Clara Murgui, Kris Pardo +2
Atom and matter interferometers are precise quantum sensing experiments that can probe differential forces along separated spacetime paths. Various atom and matter interferometer e…
Coleman-Weinberg dynamics of ultralight scalar dark matter and GeV-scale right-handed neutrinos
Clara Murgui, Ryan Plestid
We consider an extension of the Standard Model by three singlet fermions and one singlet real scalar field. The scalar is an ultralight dark matter candidate whose abundance is set…
Automatic Nelson-Barr solutions to the strong CP puzzle
Pavel Fileviez Perez, Clara Murgui, Mark B. Wise
We discuss a simple model, based on the gauge group , where the Nelson-Barr solution to the strong CP…
Axion Detection with Optomechanical Cavities
Clara Murgui, Yikun Wang, Kathryn M. Zurek
We propose a novel technique to search for axions with an optomechanical cavity filled with a material such as superfluid helium. Axion absorption converts a pump laser photon to a…
Atom Interferometer Tests of Dark Matter
Yufeng Du, Clara Murgui, Kris Pardo +2
Direct detection experiments for dark matter are increasingly ruling out large parameter spaces. However, light dark matter models with particle masses GeV are still largely un…
Flavor Anomalies and Quark-Lepton Unification
Pavel Fileviez Perez, Clara Murgui
We show that one can explain the neutral and charged anomalies in B-meson decays in the minimal theory for quark-lepton unification.The implications for flavor violating processes…
Dark Unification: a UV-complete Theory of Asymmetric Dark Matter
Clara Murgui, Kathryn M. Zurek
Motivated by the observed ratio of dark matter to baryon mass densities, , we propose a theory of dark-color unification. In this theory, the dark to visible bary…
Scalar Leptoquarks, Baryon Number Violation and Pati-Salam Symmetry
Clara Murgui, Mark B. Wise
One or more scalar leptoquarks with masses around a few TeV may provide a solution to some of the flavor anomalies that have been observed. We discuss the impact of such new degree…
Simple models with both baryon and lepton number violation by two units
Andreas Helset, Clara Murgui, Mark B. Wise
We construct simple renormalizable extensions of the standard model where the leading baryon number violating processes have . These models contain additional sca…
Leptoquarks and Matter Unification: Flavor Anomalies and the Muon
Pavel Fileviez Perez, Clara Murgui, Alexis D. Plascencia
We discuss the minimal theory for quark-lepton unification at the low scale. In this context, the quarks and leptons are unified in the same representations and neutrino masses are…
Baryogenesis via Leptogenesis: Spontaneous B and L Violation
Pavel Fileviez Perez, Clara Murgui, Alexis D. Plascencia
In order to address the baryon asymmetry in the Universe one needs to understand the origin of baryon (B) and lepton (L) number violation. In this article, we discuss the mechanism…
Baryonic Higgs and Dark Matter
Pavel Fileviez Perez, Clara Murgui, Alexis D. Plascencia
We discuss the correlation between dark matter and Higgs decays in gauge theories where the dark matter is predicted from anomaly cancellation. In these theories, the Higgs respons…

Rusa Mandal, Clara Murgui, Ana Peñuelas +1
Motivated by the persistent anomalies reported in the data, we perform a general model-independent analysis of these transitions, in the presence of light right-hand…
The Higgs and Leptophobic Force at the LHC
Pavel Fileviez Perez, Elliot Golias, Clara Murgui +1
