Jet tagging is an essential tool for physics analyses involving heavy particles decaying into hadronic final states. In the boosted regime, where bosons have high transverse momentum, their hadronic decay products are reconstructed as a single large-R jet, and identified using jet substructure and constituent-based taggers. Solutions to the classification of hadronic decays of W and Z are...

Understanding the mechanism of electroweak symmetry breaking (EWSB) remains one of the key open questions to be explored at the LHC. Measurements of vector boson polarization provide an exceptional opportunity to tackle this task due to the direct connection between longitudinal polarization and the EWSB. However, in most processes of interest the (pure) longitudinal component is by far the...
