Monte Carlo Exploration of Jet Substructure in Heavy-Flavor Events
This project is a multifaceted Monte Carlo study of jet substructure in heavy-flavor enriched events using Pythia simulations. It explores a diverse set of observables including jet axes, grooming techniques, momentum-sharing variables, N-subjettiness, and angular correlations using various tagging strategies and clustering algorithms. Heavy quarks like charm act as powerful probes of the strong force. Due to their large mass, they fragment and radiate differently than lighter quarks or gluons, encoding rich information about the dynamics of parton showering and hadronization. By analyzing the internal structure of heavy-flavor jets, we can test the predictions of quantum chromodynamics (QCD) and gain insight into how energy transforms into matter. The project evaluates the sensitivity and robustness of different observables in capturing these features, establishing a detailed vacuum reference that supports future studies of jet modifications in extreme environments, such as the quark-gluon plasma.

Dear Anselm MPS, Thank you so much for your support of my surf research this past summer. The experience allowed me to explore research options and topics in much greater depth. Not only did I learn new research methods, but I also gained valuable lessons in research ethics and the importance of collaboration. I am truly grateful for the opportunity you provided. It has helped me build a strong foundation for my future as a researcher! With gratitude, Yunhee Jang
