Description
Tau decays are notoriously difficult to detect because many particles decay with a similar signature. When searching for taus, capturing data from tau-lookalikes has been an ongoing problem, and previous global tau trigger algorithms have only had access to coarse granularity data from the calorimeters. The upgrade of the ATLAS Trigger and Data Acquisition system for the High-Luminosity Large Hadron Collider will provide high-granularity calorimeter information, offering enhanced performance required for operation during Run 4 (with 200 interactions per bunch crossing). Here we present the expected tau trigger performance, including the efficiency and background rejection.
