She then began research in the domain of partons and QCD. As a team with Migneron and others, she could create equations in the jet calculus of partons, where the viable propagators developed down instead of up, as in the Altarelli–Parisi plot. She in this way reproduced jets through Monte Carlo strategies, indicating how QCD falls from quarks and gluons can, on a basic level, be recognized. She then classified jets through the longitudinal connections between hard particles produced in the hadronic jets.
