Performance of the NA62 trigger system

Abstract

The NA62 experiment at CERN targets the measurement of the ultra-rare $K^{+}\to {\pi }^{+}\nu \bar{\nu }$ decay, and carries out a broad physics programme that includes probes for symmetry violations and searches for exotic particles. Data were collected in 2016-2018 using a multi-level trigger system, which is described highlighting performance studies based on 2018 data.
