Search for Beyond the Standard Model physics with anomaly detection in multilepton final states in pp collisions at s=13TeV with the ATLAS detector

Zero excess. Full-spectrum anomaly scan faces the beast—140 fb⁻¹ of CERN firepower, and the void blinks first. ML hunts ghosts; Standard Model still unbroken. Flavorful vector leptons, now officially on watch.
