Exploring the Dark Side of the Top Yukawa
unpublished
Studies the connection between the top Yukawa coupling and dark matter, exploring how the Higgs-top interaction constrains and motivates dark sector models.
Jet Dipolarity: Top Tagging with Color Flow
JHEP 04 (2012) 007
Introduces dipolarity, a jet observable that distinguishes whether a pair of subjets originates from a color-singlet source by measuring the pattern of radiation between them. Incorporated into the HEPTopTagger, it improves top-vs-QCD discrimination.
