Answers to some of the most fundamental questions in science, such as the mass and character of the neutrino, the nature of dark matter, or the abundance of matter over antimatter, might very well reside in the physics of the atomic nucleus. As the role of nuclei in unraveling such mysteries continues to deepen, first-principles quantum simulations, beginning from only underlying nuclear/weak...
First principles, or ab initio, nuclear theory describes atomic nuclei as systems of nucleons interacting by QCD-based chiral effective field theory (EFT) nucleon-nucleon and three-nucleon forces. In combination with chiral EFT electroweak currents, ab initio nuclear calculations can provide model-independent results with quantifiable uncertainties relevant for precision electroweak physics....
Currently, the most precise extraction of the up-down quark mixing element $ V_{ud} $ of the Cabibbo-Kobayashi-Maskawa (CKM) matrix comes from a handful of $ft$-value measurements for nuclear Fermi decays in light- and medium-mass nuclei. However, a complete extraction of $ V_{ud} $ from hadronic decays requires challenging theory determinations of hadronic-structure-dependent electroweak...
The study of the Quark-Gluon Plasma (QGP) – the most extreme state of nuclear matter produced in relativistic heavy-ion collisions – has seen great progress in recent years, owing to advances in theoretical understanding, better experimental facilities, as well as the increase in computational resources available in modern High-Performance Computing (HPC) facilities. This talk will describe...
Relativistic heavy-ion collisions form a quasi-free system of quarks and gluons known as Quark-Gluon Plasma (QGP). In addition to the formation of the QGP, these collisions also create high-momentum quarks and gluons, which will subsequently radiate a collimated spray of particles called a jet. The dynamical evolution of jets is well understood in electron-positron as well as proton-(anti)...
