Complete Initial State Radiation to off-Shell $Z^0$~PAIR Production in $e^{+}{e}^{-}$~ANNIHILATION

Dima Bardin, Dietrich Lehner, Tord Riemann

A cross-section calculation for the Standard Model reaction $e^{+}{e}^{-}\to (Z^0{Z}^0)\to f_1\overline{f_1}{f}_2\overline{f_2}$ including the effects of the finite $Z^0$~width and i…
