Physics at ATLAS: How triggers define the experiment's potential, now and in the future

dans le cadre de la procédure d’évaluation du Prof. Anna SFYRLA

The ATLAS experiment at the CERN's Large Hadron Collider (LHC) is collecting unprecedented amounts of data, enabling high energy physicists all over the world to unveil the hidden mysteries of our universe, by testing the predictions of the Standard Model, the theory that describes the building blocks of matter and how they interact. Sophisticated hardware and software systems are put in place to select detector data for analysis. This elaborate selection infrastructure, called "the trigger system", operates at extremely low latency and under stringent requirements in robustness and capacity.

In this talk I will describe the ATLAS trigger system and its challenges. I will discuss how its performance defines the capability of the ATLAS experiment to realise its envisaged physics program. I will give particular focus to the ATLAS High-Luminosity LHC upgrade, anticipated for 2026 and for which the trigger architecture has recently been redesigned.
