Searches for long-lived particles as signs of new physics at the LHC — •Sascha Mehlhase — LMU Munich

Particles beyond the Standard Model (SM) can generally have lifetimes that are long compared to SM particles at the weak scale. When produced at the Large Hadron Collider (LHC), such long-lived particles (LLPs) can decay far from the primary interaction vertex and possibly themselves interact with the detector material, leading to a wide variety of detector signatures. Such LLP signatures are distinctly different from those associated with searches for promptly decaying BSM particles that constitute the bulk of searches for new physics at the LHC, often requiring dedicated analysis and reconstruction techniques. This contribution aims to motivate searches for new long-lived particles, highlight possible signatures and challenges, and summarise the current status of searches for LLPs at the LHC.
