Physics at Virginia

Abstract: The LHC is not only the highest energy, but also the highest intensity proton-proton collider ever constructed. In 2016, the LHC exceeded its initial designed luminosity of 10^34 cm-2s-1, and since then, it has further increased to a record setting 2.06E34 cm-2s-1. The increase in luminosity has created a higher occupancy, radiation, and pileup environment, which requires an increasingly robust detector. The first of such adaptations was the CMS phase-I pixel upgrade. This pixel upgrade improved the pixel detector's bandwidth, tracking efficiency, radiation tolerance, and material budget in order to ensure physics performance up to the HL-LHC era. The next proposed tracking upgrade is a complete replacement of the inner and outer tracker. The HL-LHC Outer Tracker Upgrade is a monumental change that increases the detector's granularity, hit coverage, readout speed, triggering capabilities, radiation hardness, and cooling capabilities. This seminar will cover the construction, installation, and performance of the CMS phase-I pixel upgrade and the design, progress, and expected physics performance of the HL-LHC outer tracker upgrade.
