Particle & High-Energy Physics

This Particle & High-Energy Physics session focuses on fundamental constituents and interactions using collider, fixed-target, and neutrino-based facilities. Topics include precision Standard Model (SM) tests, electroweak symmetry breaking mechanisms, multi-loop QCD calculations, rare-process amplitudes, and global fits for CKM/PMNS parameters. Emphasis is placed on beyond-SM searches, including supersymmetric signatures, heavy vector bosons, leptoquarks, extra-dimensional excitations, axion-like particles, and dark-sector mediators. Contributions discussing parton distribution evolution, jet substructure techniques, heavy-flavor dynamics, and anomaly-driven processes are included. Detector developments—such as radiation-tolerant silicon trackers, high-granularity calorimetry, fast-timing layers, and ML-enabled triggering—form a major component. Results from LHC, HL-LHC upgrade studies, Belle II, NA62, DUNE, JUNO, IceCube, and cosmic-ray observatories will be highlighted, along with theoretical frameworks constraining high-energy phenomena.
