Sumario:This document describes the selection strategies for the upgrade trigger using a range of decay channels that are representative of the current, and planned, physics programme. The upgrade high-level trigger (HLT) follows the Run 2 trigger structure consisting of two stages, in between which the detector calibration and alignment is performed. In the first stage, HLT1, beauty and charm decays are selected inclusively, while the second stage, HLT2, uses offline-quality selections. Inclusive and exclusive trigger selections in HLT2 are presented, and the output rates, signal efficiencies, event sizes and bandwidth usage are discussed.
