BSM physics searches via decay recoil experiments - The recoiling nucleus in various forms of radioactive decay can be a sensitive probe of new physics. In the past 10 years, this field has rapidly expanded through technical advances in experimental technology.
Early Results from FRIB - The Facility for Rare Isotope Beams has started first experiments in Spring 2022. This session highlights some of the exciting new results from early FRIB experiments with rare isotopes at the limits of stability. The results span a broad range from novel nuclear structure phenomena near the proton drip line explored by precision experiments, measurements of the neutron rich nuclei in neutron star crusts, to the discovery of new isotopes and the limits of neutron stability.
Fission of Exotic Nuclei and Its Impact in Astrophysics - Very exotic nuclei are involved in the rapid neutron capture process (r-process) responsible for the astrophysical production of the heaviest elements such as actinides. Present r-process calculations require large theoretical extrapolations of the relevant fission barriers and fission yields from current data, introducing significant uncertainties. Methods for studying the fission properties of nuclei have been developed with AT-TPC, with recent results for the fission barrier and fission asymmetry of 204At in the neutron-deficient “pre-actinide” region. Neutron-induced fission also plays an important role in the r-process, with the NIFFTE collaboration’s fissionTPC at the Los Alamos Neutron Science Center making progress on precision measurements for neutron-induced fission cross sections, such as the 235U(n,f)/6Li(n,t) cross section ratio. Such measurements demonstrate significant new opportunities to extend and improve the present understanding of fission into regions of mass and charge outside currently studied actinides.
From Dense Baryonic Matter to the Quark-Gluon Plasma - Understanding the phase diagram of QCD matter was the primary motivation of the Beam Energy Scan at RHIC. New theory and experimental results which will resolve key questions are now available.
Proton Electromagnetic and Gravitational Form Factors - Form factors are a fundamental and elegant way to describe the structure of nucleons and nuclei. Their Fourier transform is closely related to the spatial distribution of electromagnetic and mechanical quantities like charge, mass and pressure, for both quarks and gluons in the nucleon. While previous investigations predominantly focused on the proton electromagnetic form factors leading to the determination of the charge and magnetization distributions, recent advances have started to unravel the gravitational form factors of quarks and gluons, where little was known. This session will bring to light the latest experimental results and latest calculations for both electromagnetic and gravitational form factors.
Lifting the Shadows: DEI Panel - This session aims to create an open space to discuss the impact that disruptive behaviors – including sexual harassment and general mistreatment – have on the workforce, and to identify community-driven efforts we can adopt to better protect those that are most vulnerable. After the presentations the speakers and audience will engage in a panel discussion directly addressing these issues in an attempt to foster alliances, share ideas, and work together to lift the shadows disrupting our community.
Precision Measurements and Fundamental Symmetries - Precision measurements of low-energy phenomena are becoming one of the main frontiers in the study of the violation of fundamental symmetries and the search for new physics beyond the Standard Model of particle physics. This session will provide an overview of some of the recent experimental and theoretical advances in the field, including studies on beta decay, measurements of symmetry-violating nuclear properties with molecules, and tests of gravity and fundamental symmetries using antimatter.
