It eventually aims for the detection of signals due to long-lived particles from Higgs boson decays predicted by various theories beyond the standard model. The applications of this study could potentially extrapolate the b-tagging performance used on tt-bar to ZH events, allowing for uncertainties for the ZH events to be analyzed. The tt-bar events are simulations of top-anti-top quark pairs that decay into b-quarks and are easily produced, being ideal for training algorithms. However, ZH events model the production of b quarks through the decay of Higgs-like, long-lived particles that are difficult to produce thus unsuitable to train algorithms. The methods used were to apply the same techniques of b-tagging on ZH and reweighting to account for differences in kinematic dependencies. Then tt-bar can be used to train algorithms for a better fit of the ZH events. However, the properties in these decay processes are different, and the ZH sample has decays more displaced from the beam interaction point than the tt-bar samples making the efficiencies different. To functionally make the efficiencies the same, cuts were applied to only include entries of b-hadron decay paths that are collinear with the path of the long-lived particles. In this way, the study concludes that the algorithms are not optimized for b-jets that originate far from the beam interaction point and algorithms need improvement for future studies.Publication Using natural language processing to identify COVID-19 spread factors from the literature to assist with mitigation of future outbreaks(Oklahoma State University, 2021-07-28) Patel, Krishna; Le, Tuan-Dung; Duong, ThanhPublication Soil moisture monitoring with LoRa radios and UAVs(Oklahoma State University, 2021-07-28) Captain, Levi; Hossain, Fahim; Messenger, Russ; Jacob, Jamey; Taghvaeian, Saleh; Ekin, Sabat
