Analytical insights on hadronic top quark polarimetry

A bstract Top quark polarization provides an important tool for studying its production mechanisms, spin correlations, top quark properties, and new physics searches. Unlike lighter quarks, the top quark’s polarization remains intact until its decay, enabling precise spin measurements. While the down-type fermions from W boson decay are known to be effective spin analyzers, charged leptons have typically been the main target for most analyses. In this paper, we investigate the relevance of global jet dynamics – considering kinematics, jet charges, and particle multiplicity – for hadronic top quark polarimetry. The formalism used allows for analytical derivations obtained throughout the manuscript, offering deeper insights into the corresponding phenomenology.
