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 …

Long-lived particles (LLPs) are a common feature in many beyond the Standard Model
theories, including supersymmetry, and are generically produced in exotic Higgs decays …

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 …

The MATHUSLA detector is a simple large-volume tracking detector to be located on the
surface above one of the general-purpose experiments at the Large Hadron Collider. This …

A hidden sector containing light long-lived particles provides a well-motivated place to find
new physics. The recently proposed MATHUSLA experiment has the potential to be …

Long-lived particles are predicted by many extensions of the Standard Model and have
been gaining interest in recent years. In this Letter we present a competitive proposal that …

A bstract Long-lived light particles (LLLPs) appear in many extensions of the standard
model. LLLPs are usually motivated by the observed small neutrino masses, by dark matter …

We explore the physics potential of using precision timing information at the LHC in
searches for long-lived particles (LLPs). In comparison with the light standard model …

We investigate the collider signatures of heavy, long-lived, neutral particles that decay to
charged particles plus missing energy. Specifically, we focus on the case of a neutralino …
