Long-lived Particles (2024)

While the long-lived particle signature itself is not something the measurements in Contur work well with, that fraction of events in which the particles with long half-lifes nevertheless decay promptly can still provide sensitivity, as shown for the first time in Probing exotic long-lived particles from the prompt side using the CONTUR method [172] for the cases of feebly-interacting dark matter, hidden sector models mediated by a heavy neutral scalar, dark photon models and a model featuring photo-phobic axion-like particles.
