Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider

Yi Zhang, Jia Liu, Jessica Prisciandaro, Federico Leo Redi, Marco Drewes, Marco Trovato, Xiao Wang, Victor Coco, Giorgia Rauco, Ennio Salvioni, Manfredi Ronzani, Patrick Foldenauer, Ahmed Hammad

Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at experiments such as the Large Hadron Collider (LHC) at CERN, these long-lived particles (LLPs) can decay far ...
