Description
In the Standard Model, the W and Z bosons acquire masses through the Higgs Mechanism, resulting in the longitudinal and transverse polarization states all being physical. However, extracting the helicity polarizations weak bosons is challenging due to their unstable nature. This is further complicated by the inherent gauge dependence in the definition of polarization vectors for massive gauge bosons. This talk presents an investigation into the gauge (in)dependence of helicity polarization in W + 1j production (with W → τ + ν) at the LHC, including full off-shell effects. Strategies for minimizing/mitigating the impact of gauge dependence are discussed.
