Galileo Galilei Institute For Theoretical Physics

Galileo Galilei Institute For Theoretical Physics

The aim of the school is to bring together PhD students with interests in low-dimensional quantum field theory, conformal field theory and integrable models, and their applications to statistical mechanics and condensed matter systems, and to help them building a solid and specialized background on these subjects. The school provides sets of postgraduate lectures covering introductory topics as well as recent developments in the field.

Relativistic fluid dynamics is a powerful universal effective theory that plays a crucial role in understanding physical systems under extreme conditions of temperature and density. These include the Quark-Gluon Plasma (QGP) created in heavy-ion collisions, matter in the early universe, colliding neutron stars, and black holes in the holographic gauge-string duality. Despite its interdisciplinary applicability and long history, the scope and foundations of relativistic hydrodynamics remain active research areas today. This workshop is dedicated to gather physicists with different expertise, those committed in applying relativistic hydrodynamics to heavy-ion phenomenology and astrophysics, alongside with researchers focusing on the foundational aspects of relativistic hydrodynamics. The aim is to foster a collaborative environment that encourages a synergic and efficient exchange of ideas from complementary realms to accelerate progress on timely problems in relativistic hydrodynamics. The experimental results and phenomenology can guide theoretical advances of relativistic hydrodynamics towards real-world applications.

Gravity and gauge theories share a rich infrared physics whose universal features manifest themselves in the context of asymptotic symmetries and their Noether charges. They clarify the soft factorization properties of scattering amplitudes, they play a role in the phenomenology of gravitational waves, and enter in the identification of new observable effects including gravitational and color memories. From the perspective of quantum gravity, they introduce new tools to understand the structure of the Hilbert space, and bring about a novel and promising approach to investigate a holographic principle for asymptotically flat spacetimes, currently pursued along two related lines: celestial and Carrollian holography. The latter exploits the Carroll structure at null infinity while the former takes advantage of powerful toolkit of conformal field theory. The vast majority of these developments have taken place in the last ten years and gave rise to research lines currently undergoing a fast growth. The proposed workshop aims at exploiting this rich and timely topic to bring together experts from all over the world, together with young researchers and students, with the goal to provide training, share results, build common grounds and foster new collaborations.

In this workshop we will explore the opportunities unleashed by progress in muon-based experiments, with particular focus on a multi-TeV muon collider. We will discuss both Standard Model precision physics and the search for new phenomena at the highest possible accelerator energies.

Topics to be discussed include: the physics of Standard Model particles at multi-TeV energies, and in particular the phenomenology across the frontier of electroweak symmetry restoration at high energy; searches for new physics at the high-energy frontier; possible uses of muon beams and related technologies for further exploration of fundamental interactions at the high-intensity frontier; synergies with other experiments in flavor, dark matter, neutrino physics, and more

This workshop aims at catalyzing the joint efforts of particle physicists and cosmologists towards the exploration of new physics with large cosmological datasets. The workshop is structured to encompass three thematic weeks dedicated to model building and testing fundamental physics in cosmology, developing novel theoretical tools to search for new physics in cosmological observables, and discussing the potential of next generation experiments to probe the plethora of new physics signals. A symposium with summary talks will conclude the workshop. A concurrent school is planned, with the aim of addressing the evolving landscape of this new field and helping participants catch up with recent developments and novel tools. An important feature of the workshop is a designated focus week, devoted to the initiation of a much-needed community white paper, summarizing the new and well-motivated particle physics models that can be tested in cosmology in the light of upcoming data and planned future experiments. The workshop nicely aligns with the expected data releases from DESI and Euclid.
