MATHUSLA and the Lifetime Frontier at the LHC

Speaker: John Paul Chou, Rutgers University

This event is part of the HEE Seminar Series.

There is substantial theoretical motivation for the production of long-lived particles at the LHC. In this seminar, I will introduce MATHUSLA, a proposed surface level detector above an LHC collision point, which aims to discover ultra-long-lived particles with lifetimes as long as O(1) s, and which would boost the sensitivity of the HL-LHC by orders of magnitude. I begin with a discussion of the theoretical motivations (from naturalness, to baryogenesis, to dark matter), before describing the theory-level detector design. Recent updates on background estimates and technical design for the proposed detector will be presented as well.
