Probing the Tri-Linear Higgs Self-Coupling
This poster explores my activities during the 2019 CCI program at Fermi National Accelerator Laboratory (Fermilab) and how they contribute to one of the ongoing projects being worked on by many employees and physicists at the LPC (LHC Physics Center). This project uses CMS (Compact Muon Solenoid) simulation samples to study the feasibility of probing tri-linear Higgs-self coupling in a process where a single Higgs is produced in vector boson scattering associated with two additional protons, i.e. , where the W bosons decay leptonically and the Higgs decays to bb. The leptons are required to have the same charge in order to suppress other standard model backgrounds. Any deviations of the Higgs-self coupling from the value predicted by the Standard Model (SM) could be indications of Beyond the Standard Model (BSM) physics. These indications would come from the observed value of an anomalous coupling, and its effects on SM values.
