Calculation of Two-Boson Exchange with Complex-Valued Masses

A new method for calculating the contribution of two-boson exchange diagrams (boxes) to the cross section for a four fermion process that involve one and two complex-valued boson masses is described. A detailed numerical analysis of the results obtained by means of this method and their comparison w...
