2WC.00001: Electron and Neutrino Interactions with Nuclei Invited Speaker: Saori Pastore Within the ab initio or microscopic framework, nuclear properties emerge from the underlying dynamics of nucleons correlated in pairs and triplets via two- and three-nucleon potentials. External electroweak probes, such as electrons and neutrinos, interact with individual nucleons and clusters of correlated nucleons via many-body electroweak currents. This approach yields a coherent picture of the nucleus and its properties, and indicates that many-nucleon effects are essential to accurately explain the available data in a wide range of energy and momentum transfer. In this talk, I will report on recent progress in ab initio calculations of nuclear electroweak structure and reactions, with emphasis on calculations based on many-nucleon potentials and associated many-body electroweak currents derived from chiral effective field theory. |

2WC.00002: Fundamental QCD effects in Nuclei: The EMC Effect and Beyond Invited Speaker: Jennifer Rittenhouse West Nuclei are made of hadrons that behave in both well-determined and potentially mysterious ways in nuclei. Experimental nuclear physics has revealed hadronic effects that appear to require a range of energy scales to understand. One focus of this talk will be on the behavior of quarks in nucleons, with a particular emphasis on how quark behavior changes when nucleons are isolated vs. in a nuclear environment, and the implications of such changes. Quark behavior in nuclei is mysterious, it was discovered in 1983 and is dubbed the “EMC effect.” The EMC effect is a rather humble effect, it deviates by approximately 10-20% from the expected quark behavior. However, as we know from the history of physics, even the most humble of experimental results can become the threads that unwind into a revolution. I will discuss the frontiers of hadronic physics today, from diquarks to hexadiquarks to nucleon spin mysteries, antiquark flavor puzzles, tetraquarks and beyond. |
