Azimuthal angular correlation as a new boosted top jet substructure

High Energy Physics - Phenomenology 2023-09-18 v2

Abstract

When a top quark is highly boosted, the WW boson from its decay has a substantial linear polarization that results in a cos2ϕ\cos 2\phi azimuthal angular correlation among the top decay products. We show that this correlation can be measured for hadronically decayed boosted tops, and its magnitude provides a way to measure the longitudinal polarization of top quark, which is an important probe of new physics that couples to top sector.
