Quantum Detectorology / Kologlu, Murat (speaker) (Yale)
I will talk about recent work studying asymptotic detector operators in weakly-coupled field theories. Detector operators describe measurements that can be performed at future null infinity in a collider experiment. [...]

A Celestial Matrix Model / Kar, Arjun (speaker) (University of British Columbia)
Understanding the proper formulation of AdS holography in two spacetime dimensions has led to fascinating progress in several directions.  The main novel ingredient compared to higher dimensions is that the asymptotic behavior of the metric is only "nearly'' AdS in a certain precise sense.  This difference allows for a very simple theory, Jackiw-Teitelboim gravity, to have a non-perturbative completion as a Hermitian matrix model.  In this talk, we propose analogous modifications of the flat space boundary conditions in two dimensional dilaton gravity.  These modifications allow a very simple theory, which we call Cangemi-Jackiw gravity, to have a non-perturbative completion as a random matrix model.  We will discuss the Lorentzian and Euclidean formulations of this model, challenges in computing its non-perturbative scattering matrix, and which of its lessons are potentially applicable to four-dimensional celestial holography..

The science and technology of DUNE / Terranova, Francesco (speaker) (Universita & INFN, Milano-Bicocca (IT))
The DUNE experiment is one of the most ambitious projects ever conceived in neutrino physics and is currently under construction at Fermilab and SURF. Its science addresses neutrino oscillations with a wide-band accelerator neutrino beam, together with astroparticles, multimessenger physics, and physics beyond the Standard Model using natural sources.

Recent ALICE results on $\psi$(2S) production / Scomparin, Enrico (speaker) (Universita e INFN Torino (IT))
Quarkonia represent a key observable for our understanding of the quark-gluon plasma (QGP) properties, and more generally for the investigation of the QCD color force in a strongly interacting environment. In heavy-ion collisions at LHC energy, significant suppression and regeneration effects were observed and analyzed in detail for the J/$\psi$. [...]

The use of Micro-Pattern Technologies in Micro-Pattern Gaseous Detectors / De Oliveira, Rui (speaker) (CERN)
The construction of Micro-Pattern Gaseous Detectors (MPGD) is the main focus of the Micro-Pattern Technologies (MPT) workshop at CERN. After a brief introduction to the activities of the MPT workshop, the presentation will retrace the technological developments for three different types of MPGDs that made it possible to obtain such detectors, which are now deployed on a large scale in particle physics experiments.The First example presented will be GEM detectors, where the step of going from a photoimageable polyimide, used in micro-electronics to passivate integrated circuits, to a particle detector able to operate more efficiently than wire chambers in the very harsh and challenging environment of high-energy physics experiments.The second example retraces the path followed to go from a stainless steel grid, used for screen printing of patterns on textiles or posters, to the production of MicroMegas detectors, used for example for the New Small Wheels (NSW) of the ATLAS experiment.The last example will deal with µ-Rwell detectors, a technology initially abandoned as soon as it appeared after the development of GEMs in 1998, but which is now revealing its full potential after being neglected for more than 20 years.

Towards a Dynamic Production of Global Land Cover Maps / Sedona, Rocco (speaker) (Forschungszentrum Jülich)
Land cover (LC) maps are a fundamental tool in a variety of fields such as climatology, ecology and geography, as their availability is crucial for the analysis of trends and recognition of patterns of phenomena that occur on the Earth’s surface. The dense Time Series of images with a worldwide coverage provided by current satellite missions allow the dynamic production of LC maps, and several methods have been recently proposed to generate maps at country, continental or global scale.

Non-conventional radionuclides in personalised medicine / Stora, Thierry (speaker) (CERN)
Abstract:Nuclear Medicine, and more particularly the so-called theranostics approach based on the combination of diagnostics and treatment drugs, has seen recent breakthroughs, originating from radionuclides made newly available notably for European academic and industrial R&D scientists.A striking example is the use of targeted radiopharmaceuticals directed to the Prostate Specific Membrane Antigen (PSMA) and Somatostatin Receptor targeted therapy with 177Lu beta-emitter. Alpha-emitting radionuclides have also been applied successfully in research and clinic. [...]
