Abstract
We present amplitude and cross-section formulas for fermion-antifermion annihilation to on-shell WW, WZ, ZZ, Wγ, and Zγ pairs in which the W and Z gauge bosons subsequently decay into fermion-antifermion pairs. The expressions include full spin-density-matrix correlations. This exact treatment yields fermion correlations that differ significantly from those obtained using W/Z-polarization-averaged cross sections followed by uncorrelated decay.Keywords
