Description

New long-lived particles (LLPs) are a feature of many extensions to the Standard Model and may elude searches for promptly decaying particles. An analysis of data collected in $pp$ collisions at $\sqrt{s}=$ 13 TeV with the ATLAS detector at the Large Hadron Collider is described, focusing on identifying signatures of jets produced by LLPs decaying to Standard Model fermions within the ATLAS calorimeter system. The most recent results of this analysis, published this year using data collected in 2016, are presented, and plans for improving this analysis with the full Run 2 dataset (2015-2018) are summarized.
