The extraordinary amount of high-quality data will open new directions for cosmology in the next few years. The increasing precision of CMB and LSS data will provide answers to current tensions and will shed light on the connections between cosmology and particle physics either behind or beyond the phenomenological success of the LambdaCDM model. At the same time, new observations at high redshifts from Lyman alpha forest and JWST and the rapid progress in gravitational-wave astronomy call for accurate theoretical predictions for new cosmological observables.

In 2024 we expect new data releases from experiments such as DESI, ACT, SPT, and new results from Euclid and JWST: the timing of this workshop is therefore very exciting. The aim of this workshop will be to discuss these latest measurements, new methodologies of data analysis, and novel theoretical developments in cosmology. The workshop format foresees invited talks, contributed talks, discussion sessions and aims in bringing together theoretical and observational cosmologists from all over the world, and providing a lively environment for a fruitful exchange of ideas on the most recent results from ACT, SPT, BICEP, DESI, Euclid, JWST, PTA and perspectives for Simons Observatory, LiteBIRD, S4, Sphere-X, Rubin-LSST and other future experiments.

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.

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.
