Study of exclusive two-body W decays with fully reconstructible kinematics

Abstract

In the framework of electroweak theory and perturbative quantum chromodynamics, we examine various exclusive decay channels of $W$ bosons that can be fully or partially reconstructed. Our findings provide predictions for the partial widths and address some gaps in previous literature. We also place a strong emphasis on understanding and estimating the associated theoretical uncertainties.
