Neutrino physics and the origin of the elements are topics intimately linked to each other and are both central to progress in the emerging revolution in multi-messenger astrophysics. Multi-messenger (gravitational waves, photons across the electromagnetic spectrum, and particles) observations of binary neutron star mergers and supernovae present a tremendous opportunity for new breakthroughs not only in our understanding of the fundamental astrophysical mechanisms that drive these phenomena but also of the origin of the elements and neutrino physics.

“How does subatomic matter organize itself?” and “What are the new states of matter at exceedingly high density and temperature?” are two of the central questions animating nuclear science today. Neutron stars are cosmic laboratories uniquely poised to answer these fundamental questions in this new era of multimessenger astronomy. Enormous progress in theory, experiment, and observation make this new era particularly fruitful for the determination of the equation of state of neutron-rich matter.

The Precision Frontier plays a unique role in the quest for physics beyond the Standard Model (SM), through (i) searches for rare or SM-forbidden processes that probe approximate or exact symmetries of the Standard Model; (ii) high precision measurements of SM-allowed processes. Experiments at the precision frontier often involve hadrons and nuclei and assessing the impact of positive or null searches requires a rigorous interface between nuclear and particle physics, linking the new physics to the hadronic and nuclear scale, where in turn one needs non-perturbative methods such as lattice gauge theory and nuclear many-body theory.

Tensor network methods are rapidly developing and evolving in many areas of quantum physics. They offer new ways of computing the properties of strongly interacting quantum matter. They provide new perspectives on theories with sign problems and/or significant entanglement. Tensor network ideas are also closely related to emerging efforts to design algorithms suitable for current and future quantum computing hardware or quantum simulation experiments. This workshop will bring together experts from a range of scientific fields with a common interest in these new methods.

Even though QCD is the underlying theory of nuclear interactions, its direct connection with various nuclear phenomena remains unclear. The fundamental questions about the role of the quark-gluon dynamics, confinement and the generation of mass remain qualitative at best. The vast majority of hadrons are unstable and in experimental measurements appear indirectly via complicated distributions of decay products. This poses substantial challenges in interpreting the experimental data and analyzing the spectrum of QCD experimentally as well as theoretically. In recent years new high-quality data from experimental facilities, together with rapid developments in ab-initio theoretical applications, have enabled us to address the most formidable questions regarding the formation of QCD bound states.

This workshop aims to bring together a group of particle theorists, nuclear theorists, and condensed matter theorists to discuss recent developments on the study of matter beyond the Landau paradigm, such as topological phases of various sorts. The study of these states of matter has transformed our understanding of phase transitions and brought together insights from different subfields of physics. These developments have applications in several areas of research in high energy, nuclear, and condensed matter physics including large N gauge theories, the QCD phase diagram, lattice field theory and topological quantum computing.

Until now, the communities of high-energy heavy-ion physics and of low-energy nuclear structure physics have been largely disconnected. To model and understand the evolution of the quark-gluon plasma (QGP), heavy-ion physics requires some input from nuclear structure physics that is typically simplified or assumed to be well-known. However, over the past decade both our understanding of the evolution of the QGP and the quality of the experimental data have become good enough to grant sensitivity to the details of the geometry of the colliding ions, and thus challenge the nuclear structure input. Measurements from collisions of 238U or 129Xe nuclei at high energy, for instance, can only be understood via the inclusion of nuclear deformation effects in the theoretical models. The need for a precise modeling of the nuclear structure was additionally emphasized in 2021 by isobar collisions at RHIC, i.e., 96Ru+96Ru and 96Zr+96Zr.

Constraining the dependence of the dense nuclear matter equation of state (EOS) on baryon density is a long-standing problem of nuclear physics. Despite active development in recent years, it is still a challenge for theoretical approaches – primarily hadronic transport simulations – to set constraints on the nuclear matter EOS at high baryon densities using the old (AGS, GSI), recent (RHIC BES FXT, HADES, NSCL), or future experimental results (FAIR, FRIB) on ratios of charged pions, neutron and proton yields and differential flow, charged particle flow, spectra, and femtoscopic correlations. Moreover, the new experiments not only measure these traditional observables with higher precision (and, in some cases, with radioactive beams), but they will also study new observables sensitive to the EOS, such as fluctuations and correlations.

Solar Fusion Cross Sections III (22-82W)

- Wick Haxton
- Aldo Serenelli
A precise understanding of nuclear reactions involved in hydrogen burning is a fundamental requirement for solar and stellar modeling. In the last decade, since the INT workshop Solar Fusion cross sections II took place, the need for accurate stellar and solar models has increased significantly. On the one hand, large-scale astronomical surveys have become the common place for studies of Galactic stellar populations, galactic archaeology, and characterization of exoplanet host stars, among other fields. Moreover, the coming of age of asteroseismology, first with Kepler, now with TESS, and in the mid-term future with PLATO, allows us to study the interior of other stars in a way that had previously only been possible for the Sun.

This program is truly multidisciplinary as it addresses fundamental questions in fields as diverse as astrophysics, gravitational physics, nuclear physics, and particle physics. The program overarching goal is to capitalize on recent discoveries that have strengthened the connection between nuclear physics an astrophysics, particularly in the area of dense, neutron-rich matter. Among the recent highlights are the most precise determination of the neutron skin of neutron-rich nuclei using electroweak probes, the identification of the most massive neutron star to date, the simultaneous determination of the mass and radius of neutron stars, and the detection of gravitational waves from the binary merger of neutron stars.

Parity-Violation and other Electroweak Physics at JLab 12 GeV and Beyond (Electronic Workshop 22-81W)
- Sonny Mantry
- Paul Souder
- Xiaochao Zheng
The focus of this workshop to fully explore the physics presented by PVDIS and similar measurements with the Solenoid Large Intensity Device (SoLID) at JLab. This not only includes the electroweak standard model study, but also rich hadronic physics topics that can be explored in parallel with or in addition to the main PVDIS measurement. Precision study of some of these hadronic physics topics also ensure accurate interpretation of PVDIS results, such as through radiative corrections. Meanwhile, the prospect of a future positron beam at JLab and an energy upgrade to 24 GeV opens up new exploratory opportunities. By the end of the workshop, we hope to not only strengthen the planned SoLID PVDIS program, but also to expand to these additional topics that can be explored in the near future.

This workshop will address the question: How does the mass of the nucleon arise? Which is listed first among three high-priority science questions identified by the National Academies of Sciences, Engineering, and Medicine (NAS) report titled An Assessment of U.S.-Based Electron-Ion Collider Science. To effectively address and understand the origin of the nucleon mass at an EIC, significant theoretical and experimental work remains. This workshop will continue to develop the science case around this high-priority science question, and help identify the concrete steps that need to be taken so that the EIC answers what is one of the most fundamental questions in modern science.

Following the joint gravitational wave and electromagnetic observations of the single binary neutron star merger GW170817, there is now strong evidence that neutron rich ejecta from neutron star mergers produces r- process elements. However, it is still not known if neutron star mergers are the dominant source of r-process elements in our galaxy.

The workshop addressed questions related to hadronization and its multiple manifestations in high-energy scattering processes. Hadronization is intrinsically connected to fundamental properties of QCD, such as confinement and the dynamical breaking of the chiral symmetry. Moreover, it plays an important role in the context of hadron and nuclear structure studies. In particular, a detailed understanding of hadronization is vital for the optimal preparation of the next generation of experiments, such as the Electron-Ion Collider.

A sound theoretical description of nuclear forces is pivotal for understanding many important physical observables over a wide range of energy scales and densities, from few-body physics to nuclear-structure observables to astrophysical phenomena. A systematic and precise theory for nuclear Hamiltonians is crucial to providing accurate predictions for these systems with controlled theoretical uncertainties, and to enable meaningful comparisons of theoretical calculations with experimental data and astrophysical observations.
