Long-lived particles at the energy frontier: the MATHUSLA physics case
We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a
comprehensive survey of standard model (SM) extensions. LLPs are a common prediction of …

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