The Evolution of the CMS Trigger System for LHC Run 3 and Beyond
A number of reported experimental anomalies in particle physics have grown in strength over the last year and will drive the next generation of LHC searches. The measured value of the muon’s anomalous magnetic moment at Fermilab and tests the lepton flavor universality by LHCb and other experiments have exceeded the 3 standard deviation threshold for evidence of new physics. Furthermore, searches for traditional dark matter candidates have not observed any positive signal. For CMS to test the full class of new physics models that can explain these results, or to perhaps directly confirm them, will require a major evolution of the experiment’s trigger strategy. In this talk I will describe my view on the current state of the particle physics field, and how the flexibility of the CMS trigger system can be leveraged to keep the experiment at the doorstep of a major discovery. In particular I will describe the “data scouting” and “data parking” paradigms that were successfully deployed in Run 2 and how they will evolve for Run 3 to address the major open questions in particle physics.
