Measuring the polarization of boosted, hadronic bosons with jet substructure observables
Songshaptak De, Vikram Rentala, William Shepherd
In this work, we present a new technique to measure the longitudinal and transverse polarization fractions of hadronic decays of boosted bosons. We introduce a new jet substruc…
