Workshops

  • We want to bring together the communities of the LHC and the EIC, with the focus on quarkonium studies and their sensitivity to hadron structure and saturation. This includes shedding light on an enhanced understanding of quarkonium production mechanisms. Reactions involving quarkonia can provide us with a novel channel to access (gluon) spin-dependent and multi-dimensional observables. At the same time, they offer us additional constraints on the collinear nucleon and nuclear parton distributions. With the EIC at present in the R&D phase, this is a most favorable time to gather both the theory and experimental communities of the LHC and EIC.

  • After a successful edition of our workshop “Towards improved Hadron Femtography with Hard Exclusive Reactions”, which was organized in July 2022 and August 2023 at Virginia Tech (Blacksburg, VA, USA), we decided to make this event annual. The goal of the workshop is to bring people together for discussing novel reactions and techniques related to Hadron’s imaging with functions such as Generalized Parton Distributions, and Hard Exclusive reactions. The special thematic for our 2024 edition will be having one day dedicated to lattice QCD and novel computing techniques for theory and analysis. The workshop will be organized in summer 2024 in Trento, by the same organizers, plus two specialists of the “special thematic”. This serie of workshop will be organized around the same thematic every 2 years in the US and every 2 years in Europe (annual event).

  • We take stock of what we have learned in the 25 years since a watershed ECT* workshop, when the now-popular effective field theory methods where first scrutinized by the nuclear-interaction community. Have potentials inspired by Chiral EFT fully replaced more phenomenological approaches? What are their phenomenological limitations? How can they be improved? Have they achieved the goal of providing a model-independent and systematic description of nuclei with controlled uncertainties? Do we understand the dynamical implications of QCD?

  • Since the seminal paper titled “Remarks on the chiral phase transition in chromodynamics” by Pisarski and Wilczek in 1984, tremendous progress has been made in our understanding of the phase structure of strong-interaction matter, e.g. it has been established from lattice-regularized Quantum Chromodynamics (QCD) that strong-interaction matter undergoes a rapid crossover transition from the hadronic phase to the quark-gluon plasma phase. Despite this progress key questions related to the fate of symmetry breaking patterns under extreme conditions of high temperature and large baryon number density as well as other control parameters, and particularly the influence of the axial anomaly on QCD phase transitions still remain elusive. These key questions are not only of theoretical interest but also closely related to the on-going ultra-relativistic heavy-ion collisions experiments. This workshop aims at bringing together experts in the field as well as young practitioners to discuss the latest developments on these studies.

  • The recent measurement of the spin polarization of particles produced in nuclear collisions has opened a new frontier for the study of strong-interaction matter under extreme conditions. Future experimental efforts will measure spin observables with unprecedented precision. On the theoretical front, there is rapid progress in discovering new effects that polarize spin. However, the understanding of these new effects as well as their implementation in dynamical frameworks such as quantum hydrodynamics and kinetic theory are still under development. The goal of the workshop is to gather experts from both theory and experiment to determine the state-of-the-art knowledge in the field, to exchange ideas and methods, and to initiate new developments.

  • Kaonic, antiprotonic, muonic and pionic atoms, as well as the so-called “onia”, are exotic systems where one or more sub-atomic particles are replaced by a different particle of identical charge. In particular kaons, pions or antiprotons replacing one of the orbital electrons are used to form hadronic atoms, while a muon forms a leptonic exotic atom. Finally, in a “hydrogen-like” configuration, a bound pair of a particle and its antiparticle or of two leptons represents an exotic system called onium; some of these states, like muonium, positronium and pionium, have been already experimentally observed but others may exist; their observation could enable important tests for both QCD and QED. All these exotic atoms represent unique tools for testing the foundation of electromagnetic, strong and even gravitational interactions. It is thus the right time for discussing synergy and exchanging information between the physics communities involved in exotic atoms studies.

  • Accelerator neutrino oscillation experiments have the potential to revolutionize our understanding of fundamental physics, including: characterizing charge-parity violation in the lepton sector; determining the neutrino mass ordering; and exploring physics beyond three-flavor neutrino mixing. However, the next generation of long baseline experiments (DUNE and Hyper-K) require precise control over the systematic uncertainties in their analyses. The most challenging uncertainties come from the modeling of neutrino-nucleus interactions and are related to subtle details of the pertinent nuclear physics, such as those of the target nucleus ground state, and the transport of hadrons through the nuclear medium. Confronting such uncertainties requires significantly improved theoretical models as well as targeted measurements with the current generation of experiments to inform model development. This workshop will bring together neutrino oscillation experimentalists, nuclear theorists and those measuring neutrino-nucleus interactions, and will provide a unique opportunity for cross-field discourse.

  • This workshop gathers specialists from theoretical and experimental condensed matter and atomic physics as well as nuclear and gravitational physics to discuss in an interdisciplinary way the concept of Bose-Einstein condensation and its realizations in different areas of the physical sciences. It is the 2024 edition (coinciding with the centenary of the pioneering first work by Satyendra Bose) of a series of key events that started in Levico (near Trento) back in 1993 and were instrumental to the impressive developments that research on BECs displayed in the last three decades. As compared to other events focussing on specific systems, the distinctive feature of our workshop will be its commitment to have a broad spectrum of participants and topics, with the goal of fostering and nurturing existing interdisciplinary connections and facilitating new, unexpected ones. In particular, themes will include condensation in gases of ultracold atoms, quasi-particles (magnons, excitons, polaritons) in solids, light; emergence of universality and criticality in the non-equilibrium statistical mechanics of condensates; condensates in gravitation and cosmology. The structure of the workshop will be designed with a specific attention to stimulate unexpected long-range connections between distinct fields.

  • The study of the QCD phase diagram in the high-muB region is a key avenue toward understanding strongly interacting matter under extreme conditions. First accurate data in the collision energy region around 10 GeV, corresponding to baryo-chemical potentials of several hundred MeV, became available recently, with the completion of the Beam Energy Scan at RHIC. Hadronic and electromagnetic observables were the main addressed topics. The next breakthrough is expected with the CBM/HADES experiments at FAIR/GSI and the proposed NA60+ experiment at SPS/CERN that will take data at interaction rates larger by at least two orders of magnitude, allowing a much more accurate study of electromagnetic probes and first results on heavy-quark production. Following an exploratory workshop held at ECT* in 2021, we now aim at substantial progress in reviewing currently available results, analyzing the physics potential of the forthcoming experiments, and discussing first actual predictions for the future measurements. We will also review the progress on new detectors for high-luminosity experiments, identifying possible developments and synergies between the various projects.
