Neutron Stars – Nature’s most extreme laboratory
/ Noronha-Hostler, Jacquelyn (speaker) (University of Illinois Urbana Champaign)
When intermediate mass stars have spent their fuel, a powerful explosion occurs called a supernova that then undergoes a gravitational collapse into a neutron star. Neutron stars reach the largest densest in the universe at their core, anything denser would collapse into a black hole. [...]

Exploring Collective Dynamics in Small Collision Systems with ALICE at the LHC
/ Sarkar, Debojit (speaker) (Niels Bohr Institute, University of Copenhagen, Denmark)
The observation of collective-like behaviors in pp and p–Pb collisions at LHC energies has sparked debate about the similarities between the dynamics of small systems and heavy-ion collisions. In this talk, we present our latest published results on long-range two-particle azimuthal correlations, utilizing the unique acceptance of the mid- and forward-rapidity detectors in ALICE [...]

The Alpha Magnetic Spectrometer (AMS-02)
/ Gargiulo, Corrado (speaker) (CERN)
The Alpha Magnetic Spectrometer (AMS), operating on the external truss of the International Space Station (ISS) since 2011, has recorded over 240 billion cosmic ray events, significantly advancing high-energy astrophysics and the search for dark matter. To enhance its capabilities, AMS is being upgraded with a new large (8m2 of sensors) silicon tracker layer (Layer-0), which will increase particle detection acceptance by 300%, enabling deeper investigation of the cosmic ray signature.
Following a global qualification campaign, all flight components, including sensors, electronics, and mechanical sub-systems, have been built and are now being assembled at CERN, where final detector mapping and test beam calibration will take place [...]

Search for a new 17 MeV resonance via e+e− annihilation with the PADME Experiment
/ Spadaro, Tommaso (speaker) (INFN e Laboratori Nazionali di Frascati (IT))
The PADME experiment at the Frascati National Laboratory of INFN has performed a search for the hypothetical X17 particle, by observing the product of the collisions of the positron beam from the DAΦNE LINAC on a diamond fixed target.The beam energy has been varied in the range 265–300 MeV, corresponding to values of √s between 16.4 and 17.5 MeV, completely covering the CoM region identified by the ATOMKI collaboration as significant for observing the postulated X17 particle.The result of the analysis shows an about 2-sigma excess corresponding to the mass indicated by the ATOMKI experiment. A new data taking campaign, with an improved detector is planned to start in the summer of 2025, with the aim of pushing forward the sensitivity of the search.

Geometrical Methods of Effective Field Theories (HEFT workshop)
/ Manohar, Aneesh Vasant (speaker) (Univ. of California San Diego (US))
I discuss recent progress in using geometrical methods to compute radiative corrections in quantum field theories, and give some applications to SMEFT and ChPT. I will also briefly discuss infinite anomalous dimensions in EFTs..

Superconducting nanowire detectors: from quantum science to high-energy physics
/ Korzh, Boris Alexander (speaker) (Universite de Geneve (CH))
Superconducting nanowire detector development was driven largely by quantum science during the last decade, but emerging high-energy physics applications are motivating a new wave of breakthroughs. They are capable of detecting photons (X-ray to far-infrared), low energy electrons, ions and neutral molecules and most recently have been tested for relativistic particle detection [...]
