Enhancing to an Observable Level in the Two-Higgs-Doublet Model
Matthew Black, Alexis D. Plascencia, Gilberto Tetlalmatzi-Xolocotzi
As a result of the helicity suppression effect, within the Standard Model the rare decay channel has a decay probability which is five orders of magnitude below c…
Two-Higgs-Doublet Model and Quark-Lepton Unification
Pavel Fileviez Perez, Elliot Golias, Alexis D. Plascencia
We study the Two-Higgs-Doublet Model predicted in the minimal theory for quark-lepton unification that can describe physics at the low scale. We discuss the relations among the dif…

Pavel Fileviez Perez, Hiren H. Patel, Alexis D. Plascencia
We discuss the prediction of the boson mass in a simple extension of the Standard Model () with a real scalar triplet. A shift in the mass as reported by the CDF…
Theory of Dirac Dark Matter: Higgs Decays and EDMs
Pavel Fileviez Perez, Alexis D. Plascencia
We discuss a simple theory predicting the existence of a Dirac dark matter candidate from gauge anomaly cancellation. In this theory, the spontaneous breaking of local baryon numbe…

We point out unique relations between the decay widths for leptoquarks and Higgs bosons that can be used to test the unification of quarks and leptons at the TeV scale. We discuss…
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
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…

New sources of CP violation beyond the Standard Model are crucial to explain the baryon asymmetry in the Universe. We discuss the impact of new CP violating interactions in theorie…

Assessing Perturbativity and Vacuum Stability in High-Scale Leptogenesis
Seyda Ipek, Alexis D. Plascencia, Jessica Turner
We consider the requirements that all coupling constants remain perturbative and the electroweak vacuum metastable up to the Planck scale in high-scale thermal leptogenesis, in the…
Black hole superradiance and polarization-dependent bending of light
