Abstract

In this project, I present a High-Energy Physics research proposal in the CMS experiment of the Large Hadron Collider. The experiment has built and deployed a multipurpose detector capable of registering the proton-proton collisions delivered by the accelerator, with excellent particle reconstruction and identification capabilities and an acquisition rate of up to 1000 interactions per second. With the high-luminosity upgrade of the collider, which will bring the instantaneous luminosity to 75 Hz/nb, the CMS experiment will be revamped to make the most of the unprecedented amount of data that will be produced - L = 3000 fb-1 of pp collisions over the full experimental run. Those data will open up new avenues of research within CMS, including the accurate measurement of properties of the Higgs boson and new searches for physics beyond the standard model. The CMS Trigger and Data Acquisition System will be upgraded to deliver an event storage rate of 7.5 kHz, corresponding to a data throughput of 60 GB/s. My goal is to coordinate the design, initial implementation and documentation of the High-Level Trigger sector of the system, culminating in the publication of the CMS DAQ Technical Design Report for the Phase-II upgrade, to be published in early 2021.
