Recent years have seen major advances in our understanding of the quark and gluon content of hadrons. Yet, achieving a fully quantitative three-dimensional picture of parton distributions within nucleons remains a critical challenge in QCD. We propose a workshop titled “Toward Next-Generation QCD for Hadron Imaging: High-Precision Global Analysis and Lattice QCD" with the goal of fostering a focused, synergistic effort toward the high-precision extraction of GPDs. This workshop will bring together experts in global QCD analysis, lattice QCD, and advanced data analysis techniques to develop a common framework for GPD reconstruction. We also plan to include experts in TMD studies to explore methodological overlap and complementarity. Key goals include refining theoretical formulations, integrating lattice constraints into global fits, and advancing strategies to solve the underlying inverse problems using modern tools. In contrast to previous ECT* workshops, which emphasized interpretative aspects of hadron structure, this workshop will focus on theoretical and numerical strategies for precision extraction. By doing so, it aims to create a new momentum for quantitative hadron tomography. The workshop will also promote interdisciplinary collaboration by bringing together students, postdoctoral fellows, and senior scientists, fostering the exchange of innovative ideas across all career stages.

Describing the interaction between nucleons and understanding how nuclei behave at the extremes of stability are two major goals of modern nuclear theory. Electroweak responses in nuclei from the low-energy to quasi-elastic regimes provide a means to address these aims. The study of electromagnetic nuclear responses has a direct impact on understanding the correlations of nucleons inside halo systems, determining the slope of the symmetry energy, and illuminating the nature of short-range correlations in nuclei. Moreover, reliable predictions of electroweak responses are pivotal for fundamental symmetries research, and have direct implications for a deeper understanding of astrophysical phenomena. The main aims of the program will be to assess state-of-the-art ab initio frameworks to study nuclei and nuclear matter, to identify possible benchmarks of the available methods, and to determine how we can use our frameworks to consistently make inferences about the nature of the nuclear interaction from terrestrial experiments and astrophysical observations. To gain insight into how we can improve our methods, we will include experts studying the dynamics of other strongly-interacting quantum-systems; for instance, such as systems encountered in condensed-matter and atomic physics. Further, we will emphasize how we can use advances in AI/ML to improve our models and assess theoretical uncertainties, as well as discussing how quantum computing could allow us to study the dynamics of nuclei and nuclear matter.

The combined “standard models" of fundamental interactions and cosmology leave a number of questions about the observed universe without answer. Outstanding puzzles include the origin and nature of neutrino mass, the origin of the matter-antimatter asymmetry in the universe, and the nature of dark matter. Low-energy processes involving neutrinos, hadrons, and nuclei have the potential to shed light directly or indirectly on some of these great mysteries. Given the potentially very high impact of the experimental program of electroweak and Beyond the Standard Model (BSM) physics with nuclei and the crucial need for the corresponding theory, we propose a DTP focused on ‘nuclear theory for new physics’. Through lectures and problem-solving sessions this DTP will provide nuclear theory students the motivation and context for electroweak and BSM studies with nuclei as well as the basic theoretical and computational tools needed in these studies. This DTP aims to establish a common ground for nuclear theory students in different sub-communities interfacing in the study of electroweak and BSM physics with nuclei: phenomenology and Effective Field Theory, lattice QCD, and nuclear structure. The concepts and tools presented at this DTP will prepare the students to apply cutting edge methodologies to challenging problems in the field and to identify new directions.

This workshop will address the low-energy probes that access the electroweak lepton-quark interactions using atomic nuclei, elaborate on connections between beta decays, parity violation, and the physics of exotic and ordinary atoms, and study the impact of these probes in a broader context through the global electroweak fit to low-energy and collider data in the Standard Model and beyond. The atomic, nuclear, and particle communities often work separately. This interdisciplinary workshop will bring together experts from these fields, both theorists and experimentalists, and create an exciting context for them to interact, recognize intersections, foster connections, and seek possibilities to guide the planning of future scientific programs.

Recent years have seen an explosion of cross-disciplinary research linking machine learning and theoretical physics. In this workshop, we focus on generative methods as applied to lattice field theory, with QCD as a long-term target. With many approaches being explored at various levels of maturity (normalising flow, including stochastic and continuous normalising flow, diffusion models, transport models, ...) and a deepening understanding from the perspective of theoretical physics (links to the renormalisation group, gauge symmetries, stochastic quantisation, random matrix theory, ...), it is time to take stock and constructively assess the applicability of the methodology and future perspectives in the field. The meeting will bring together researchers from the theoretical physics community, active in lattice field theory and statistical physics, with researchers in ML, to optimise the possibility of knowledge exchange. As the field is evolving rapidly, we take care to invite proponents of new and promising methods, as they are developed between the submission of the proposal and the delivery of the workshop. The key outcome will be the advancement of a common foundation and the agreement on a set of targets for the short and intermediate term.

The symposium addresses experimental and theoretical studies of the equation-of-state (EoS) of isospin asymmetric nuclear matter, with its implications in astrophysics. The scientific sessions of NuSym26 will present latest results and new ideas on probes of the symmetry energy below and above saturation density from laboratory experiments as well as from astrophysical observations, gravitational waves and supernova neutrinos.

Neutron-star mergers and core-collapse supernovae are among the most promising sites for the synthesis of heavy elements in the universe. These astrophysical phenomena bring together a rich interplay of general relativity, neutrino physics, nuclear reactions, and magneto-hydrodynamics (MHD). Among these factors, magnetic fields are increasingly recognized as playing a pivotal role in shaping the dynamics and nucleosynthetic outcomes of these events. Recent observational breakthroughs, from the detection of gravitational waves (e.g., GW170817) with EM counterparts and increasingly detailed supernova spectra, demand a deeper theoretical understanding of how magnetic fields interact with nuclear physics and influence heavy-element nucleosynthesis. At the same time, simulations of these events now routinely include magnetic fields and detailed neutrino transport demonstrating the potential of magneto-rotational supernovae and neutron-star mergers to produce rich nucleosynthesis yields including the heaviest elements produced by the r-process and set the stage for GRB jets. Given all these recent developments we are at a critical moment to advance the field but there is a need for detailed discussions and interactions among nuclear physicists, astrophysicists, and computational modelers to address key open questions and make the most of the available observational datasets and computational resources. This workshop aims to bring these communities together.

Planar fermions underpin much interesting physics in layered systems and are extensively studied in condensed matter physics; for instance, electronic properties of graphene have long been understood in terms of relativistic fermions centred on Dirac points in momentum space, but the influence of interactions between charge-carrying degrees of freedom is less well-understood and remains an active field of study. More recently, layered structures exhibiting moiré patterns—arising from slight rotational misalignments or lattice constant mismatches between individual layers—have emerged as highly tunable platforms for studying interacting relativistic fermion systems. Quantum fermions in 2+1d also present many theoretical challenges, and there is an encouraging parallel renaissance of interest involving among others workers in large loop-order perturbation theory, functional renormalisation group, conformal bootstrap, and lattice simulation, for whose practitioners such systems encapsulate essential challenges for their respective agendas. Another recent promising technique is quantum simulation, which is particularly suited for dynamics due to its use of unitary operations. Current digital quantum hardware available for cloud computing offers on the order of a hundred physical qubits, with analog computers offering on the order of a thousand qubits. These numbers are promising for out-of-equilibrium simulations of planar systems, and theoretical progress has been made for algorithms involving computers based on fermionic components rather than the usual bosonic qubits, which holds promise for efficient fermionic simulations. A week-long workshop hosted at ECT* is a perfect forum to assemble attendees spanning this diverse community, stimulate knowledge exchange, and spawn fresh research directions.

Exotic atoms—where electrons are replaced by heavier particles such as muons, pions, kaons, antiprotons or heavier antinuclei—serve as very powerful precision laboratories to investigate the fundamental interactions and symmetries of nature. By generating and measuring these atoms and their transitions, we are able to uniquely explore low-energy QCD effects through hadronic atoms, test strong-field QED, and, in very recent years, search for interactions that go beyond the Standard Model (BSM) and their carriers (dark bosons). The search of antinuclei in cosmic rays is also a possible way to detect BSM particles. Recent milestones in exotic atoms include the first-ever 2023-2024 measurement of the strong-interaction-induced energy shift and width in kaonic deuterium by the SIDDHARTA-2 collaboration, as well as highly accurate spectroscopic measurements of kaonic neon and test measurements of muonic atoms probing QED at field strengths approaching and exceeding the Schwinger limit. Studies of antiprotonic and pionic atoms in heavy nuclei are also setting new limits on possible fifth forces. The NEW-EXOTICA workshop aims to provide, for the first time, a unified platform for expert and young experimentalists and theorists from major universities and institutions working in the field and from major international facilities—including DAFNE, J-PARC, PSI, CERN-ELENA, and RIKEN—to share their latest findings, engage in deep discussions on theoretical frameworks, and define future paths for exotic atoms joint research.

The past fifteen years have seen a remarkable evolution in our perception of hadron structure. Especially within the past five years, modern experimental facilities, new techniques for the continuum bound-state problem, and progress with lattice-regularized QCD have begun pointing to a crucial role for soft quark + quark (diquark) correlations in forming the structure of hadrons. For instance, theory indicates that diquark correlations within baryons are a necessary consequence of emergent hadron mass mechanisms; that the presence and character of diquark correlations make heavy impressions on helicity dependent baryon structure functions; experiments have uncovered signals for such correlations in the flavour-separation of the proton’s electromagnetic form factors and the appearance of zeroes therein; and the possibility that diquarks play a role in forming some of the XYZ states is hotly debated. Today’s key questions are: “If diquark correlations are real, then where should physics best look to find, understand, and exploit them?” This workshop will gather experimentalists, phenomenologists, and theorists to undertake a critical review of existing information, consolidate the facts, and therefrom develop a coherent, unified picture of hadron structure.

The proposed workshop will cover one of the most outstanding topics of strong interaction physics which is the dynamics of quark-gluon interaction in the nuclear medium. Understanding how quarks and gluons behave as they are embedded in the nuclear medium is essential to series of strong interaction phenomena as modification of quark and gluon distributions of nucleons in nuclear medium, hadron-quark gluon transition at extreme nuclear environment, role of the super-fast quarks in nuclear PDF’s at very large Q2 and its relevance to the composition of superdense cold nuclear matter. Expected outcome of the workshop will be theoretical analysis of the new series of experimental data that will be available from Jefferson Lab and LHC as well as discussion of new theoretical approaches which are currently being developed by several groups also for the experimental program of the future Electron Ion Collider.
