Abstract
In mid-2022, the Large Hadron Collider (LHC) at CERN began Run 3. In this investigation, the LHC will produce proton-proton collisions at the energy of 13.6 TeV, in collaboration with the CMS experiment, to search for significant evidence of the Standard Model Higgs boson decaying to two muons. Specifically, our group will search for this interaction via the vector boson fusion (VBF) channel.
Furthermore, upgrades to CMS need to be performed in preparation for the High-Luminosity Large Hadron Collider (HL-LHC) project. Specifically, the CMS Outer Tracker (OT) will now be able to single out beam crossings with tracks in excess of 2 TeV of transverse momentum and associate physics objects with the high transverse-momentum tracks. The OT will replace the strip tracker and is expected to operate for nearly a decade without any needs for repairs. These operations will be partially conducted at the Fermi National Accelerator Laboratory located just outside Batavia, Illinois. The Fermilab OT group is responsible for the assembly and testing of over 1,250 PS modules and 1000 2S modules. Overall, in combination with
the OT upgrades this will increase the integrated luminosity of the LHC by a factor of 10.

- Public Abstract (ETD)
- The existence of the Higgs boson was recently discovered experimentally in 2012, via the Large Hadron Collider at CERN in Geneva, Switzerland. This particle accelerator is a 27 km ring that shoots two high-energy particle beams, traveling at nearly the speed of light, at one another. Their collisions produce extraordinary physics events which are later studied by researchers for various projects. This finding was a monumental milestone in the field of high energy physics as it expanded the Standard Model of Particle Physics. This theory classifies the fundamental structure of matter called elementary particles and currently describes three of the four known fundamental forces. To authenticate this particle’s placement into our model, rigorous testing must completed to prove its validity. Our group at the University of Iowa has had the pleasure to collaborate with researchers around the globe, associated with CMS, in order to complete this task. Lastly, for the continuation of the LHC, preparations must be made to upgrade the current machinery. The new, exciting HL-LHC project will require improvements to the OT in order to withstand higher amounts of radiation. Assembly will conducted partially at Fermilab’s Silicon Detector Facility (SiDet).
