Search for long-lived massive particles in events with displaced vertices and missing transverse momentum in s = 13 tev pp collisions with the atlas detector

Research output: Contribution to journalConference article

Abstract

A search for long-lived particles at the electroweak scale, which are predicted by a number of theories beyond the Standard Model, such as long-lived gluino in Split Supersymmetry, is presented. The search uses 32.7 fb 1 of 13 TeV pp collision data collected by the ATLAS detector at the LHC, and explores a multi-track vertex displaced from the collision point of proton-proton beams. The observed yield is consistent with the expectation from the background only hypothesis, resulting in 95% confidence-level exclusion of the long-lived gluino with masses up to 2.4 TeV at around τ = 0.17 ns.
