Optimizing trigger-level track reconstruction for sensitivity to exotic signatures

Many compelling beyond the Standard Model scenarios predict signals that result in unconventional charged particle trajectories. Signatures for which unusual tracks are most conspicuous feature of event pose significant challenges experiments at Large Hadron Collider (LHC), particularly trigger. This article presents a study track-based triggers representative set long-lived and signatures upcoming High Luminosity LHC, as well resulting recommendations target parameters hardware-based tracking system. Scenarios studied include large multiplicities low momentum produced soft-unclustered-energy-pattern model, displaced leptons anomalous prompt predicted Supersymmetry model with staus, hadrons Higgs portal scenario scalars.
