Rare charm decays at LHCb / Colonna, Marco (Tech. U., Dortmund (main)) /LHCb Collaboration
The LHCb experiment collected the world's largest sample of charmed hadron decays. This data set allowed the LHCb collaboration to provide the most precise results for rare charm decays with two leptons in the final states. [...]

Particle-antiparticle asymmetries in hadronic charm decays at LHCb / Balzani, Luca (Tech. U., Dortmund (main)) /LHCb Collaboration
The Charm sector offers a unique environment to study processes such as neutral meson mixing and $CP$ violation, and the LHCb experiment plays a pivotal role in these investigations. Due to the smallness of the parameters describing these phenomena, the high precision measurements LHCb provides allow to perform rigorous null tests of the Standard Model.This proceeding presents some of the latest results from the LHCb collaboration, focusing on measurements of mixing and $CP$ violation observables in the Charm sector..

LHCb highlights / Szabelski, Adam (NCBJ, Warsaw) /LHCb Collaboration
The LHCb collaboration has provided many results related to the DISCRETE conference topic. Namely, these concern $CP$ violation in beauty and charm meson decays as well as in baryon decays and searches for lepton flavour violation. [...]

Status and prospects of the NA64 experiment / Banto Oberhauser, Benjamin (Zurich, ETH) /NA64 Collaboration
The NA64 experiment at the CERN SPS has obtained the world-leading constraints in the search for Light Dark Matter (LDM) candidates with sub-GeV masses using an electron beam. Most recently, the complementarity of the physics case with the NA64$e^{+}$ and NA64$\mu$ programs has been established, in particular following the first results for searches with high-energy muons.

How large could CP violation in $B$ meson mixing be? Implications for baryogenesis and future searches / Miró, Carlos (Valencia U.) ; Escudero, Miguel (CERN) ; Nebot, Miguel (Valencia U.)
It is well-known that CP violation is one of the necessary ingredients to generate the observed matter-antimatter asymmetry of the Universe. Neutral $B$ mesons naturally exhibit CP violating oscillations, such that the amount of CP violation in their mixing can be directly related to the baryon asymmetry through the $B$-mesogenesis mechanism.

Generalized symmetries in particle physics / Davighi, Joe (CERN)
In this talk we review various notions of generalised global symmetry: higher-form symmetry, higher-group symmetry, and non-invertible symmetry. All these notions have had profound impact on quantum field theory research in the last decade. [...]

App-Based Tool for Automatic Controller Parameters Assessment for Power Converters in Particle Accelerator Facilities / Maestri, Sebastian O (Buenos Aires, CONICET ; La Plata U.) ; Le Godec, Gilles (CERN) ; Michels, Olivier (CERN)
Regulation coefficients assessment in a particle accelerator power conversion system depends on the topology, the magnet and the desired transient response. The series/parallel combination of a generic power converter (a brick) to develop a larger one (e.g., the SIRIUS power converter family developed at CERN) allows to feed several magnets with different parameters.

RPP Model Trends Across Technology Nodes for the MC Simulation of SEUs in Commercial Bulk Planar CMOS SRAMs Under Proton Irradiation / Şerban, Alexandra-Gabriela (CERN ; Bucharest U. ; Bucharest, IFIN-HH) ; Coronetti, Andrea (CERN ; IES, Montpellier ; Unlisted, DE) ; García Alía, Rubén (CERN) ; Salvat-Pujol, Francesc (CERN)
The ubiquitous use of electronic devices in high-radiation environments requires robust methods for assessing and improving their resilience against single-event effects (SEEs) and, especially, single-event upsets (SEUs). In this study, SEU production induced by protons below 500 MeV in three commercial bulk planar static random access memories (SRAMs) manufactured on different standard CMOS technology nodes (from 250 to 40 nm) is investigated employing the Monte Carlo (MC) particle-transport code FLUKA.

Characterization of the FOOT neutron detectors for nuclear fragmentation measurements at the n_TOF facility / FOOT Collaboration
FOOT (FragmentatiOn Of Target) is an applied nuclear physics experiment with the aim of performing high precision cross section measurements for fragmentation reactions of interest in hadrontherapy and radiation protection in space. The physics program of the experiment foresees a set of measurements with light ion beams, such as C and O, in the energy range of 100–800 MeV/u interacting with tissue-like and shielding material targets.
