ABSTRACT
The Standard Model of particle physics has been a successful theory, agreeing with decades of experimental observations involving weak, electromagnetic, and strong interactions. The discovery of the Higgs boson at the LHC was further confirmation of this success. However, the Standard Model remains an incomplete theory. The precise measurements of the properties of the Higgs boson at the LHC could provide insight into new physics beyond the Standard Model. This research focuses on exploiting the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) to search for new particles, study the decay of Higgs bosons, carry out precision measurements of other Standard Model (SM) processes, use jet substructure to reconstruct high-momentum objects, and extend the capabilities of the CMS particle-tracking detector to increase its acceptance and tolerance to high collision rates. The research activity will also foster collaboration with high school teachers and students through the QuarkNet and Science Olympiad outreach efforts, and foster female participation in STEM disciplines through the university's Women in Science and Engineering initiative.
This research will search for subtle signatures of Beyond Standard Model (BSM) physics using advanced methods for identifying rare signals and addressing systematic uncertainties. These include detailed studies of the properties of the Higgs boson, extending the search program for BSM physics, and systematically improving techniques to maximize the physics potential. This research will also extend the capabilities of the CMS tracking detector to handle conditions at the High Luminosity LHC, extend its geometric coverage, and add tracking information to the far-forward particle flow algorithm. In addition, studies will be performed on the properties of highly Lorentz-boosted SM Higgs bosons decaying to bottom quark-antiquark pairs to fully explore the Higgs coupling to quarks, as well as to search for new phenomena in unexplored signatures at higher masses, such as new heavy vector bosons. This program will also develop and maintain object reconstruction for heavy- and light-flavor jets, as well as perform measurements of SM physics processes including production of W/Z/gamma in association with heavy flavor jets, and detailed understanding of the quantum chromodynamic evolution of jets.
This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

The research done with this grant advanced the knowledge of humanity to fundamental interactions at the smallest scales ever achieved to date. Our research has primarily focused on understading of sprays of particles called "jets" from the strong interaction that are produced in nearly all proton-proton collisions at the Large Hadron Collider, including identification of these particles from heavy quarks and other heavy particles. This has applications in precise measurements of collisions at the LHC that produce electroweak bosons in association with jets from heavy quarks, as well as studies of the evolution of these jets via the strong interaction. We also performed searches for new physics beyond the standard model with these jets. We have contributed strongly to the overall comissioning and operation of the CMS detector in preparation for Run 3 of the LHC, as well as significant contributions to software and data analysis. In addition, the group was involved in the planning exercises for the next generation of colliders, the "Snowmass" process.
Our group is deeply committed to providing a more inclusive and equitable environment in our field and in our group, We are committed to improving the participation of all people regardless of background, especially including historically underrepresented groups in our research, as evidenced by our involvement in the Education and Public Outreach component of the HL-LHC upgrade program, mentorship programs for the US-CMS collaboration, and participation in AGEP-GRS fellowships for our students.
We have published several papers with several more on the way, along with a large number of leadership positions within the CMS Collabortion. There were 3 graduate students who obtained their PhD's, and permanent job placement for two former postdocs in academic and CERN positions, including one who is now joining the faculty at UB after a time at Argonne National Laboratory.
