Title: Flavor Patterns of Fundamental Particles from Quantum Entanglement? Abstract: The Cabibbo-Kobayashi-Maskawa (CKM) matrix, which controls flavor mixing between the three generations of quark fermions, is a key input to the Standard Model of particle physics. In this talk I will identify a surprising connection between quantum entanglement and the degree of quark mixing. Focusing on a specific limit of 2→2 quark … Read More

Title : Predicting the dark matter – baryon abundance ratio. Abstract : We discuss relaxation solutions to the dark matter – baryon coincidence problem in the context of QCD axion dark matter. In relaxation solutions, a moduli dynamically adjusts the mass of dark matter and baryons until their energy densities are O(1) the same. Because the QCD axion is heavily connected to QCD, scanning the QCD … Read More

Title: The Quality/Cosmology Tension for a Post-Inflation QCD Axion Abstract: The QCD axion is not only a leading contender as a solution to the Strong CP problem, it is also a natural dark matter candidate. In particular, the post-inflationary axion is particularly attractive because of the possibility of a unique prediction of the axion mass if axion makes up all of dark matter. … Read More

Title: Higher Order Flavor Sum Rules  Abstract:   Hadronic physics is notoriously challenging to study due to the non-perturbative nature of QCD. Although significant advances have been made in recent years, there are still no reliable methods for calculating observables in multibody hadron decays. As a result, flavor physics predictions, which rely on the approximate SU(3) flavor symmetry of QCD, remain the state … Read More
