Comparison of two hardware-based hit filtering methods for trackers in high-pileup environments

Understand

As experiments in high energy physics aims to measure increasingly rare processes, the experiments continually strive to increase the expected signal yields.

• In the case of the High Luminosity upgrade of the LHC, the luminosity is raised by increasing the number of simultaneous proton-proton interactions, so-called pile-up.
• This increases the expected yields of signal and background processes alike.
• The signal is embedded in a large background of processes that mimic that of signal events.
