PhyGHT: Physics-Guided HyperGraph Transformer for Signal Purification at the HL-LHC

arXiv CS.LG

ArXi:2602.20475v2 Announce Type: replace-cross The High-Luminosity Large Hadron Collider (HL-LHC) at CERN will produce unprecedented datasets capable of revealing fundamental properties of the universe. However, realizing its discovery potential faces a significant challenge: extracting small signal fractions from overwhelming backgrounds dominated by approximately 200 simultaneous pileup collisions. This extreme noise severely distorts the physical observables required for accurate reconstruction. To address this, we
