LUMINOSITIES FOR VECTOR-BOSON-VECTOR-BOSON SCATTERING AT HIGH-ENERGY COLLIDERS

We derive exact expressions for luminosities of massive vector-boson p airs which can be used to describe the cross sections for processes in hadron collisions or e(+)e(-) annihilation which proceed via two-vect or-boson scattering. Our approach correctly takes into account the mut ual influence of the emission of one vector boson on the emission of a second one. We show that only approximately the exact luminosities ca n be factorized into convolutions of single-vector-boson distributions . Numerical results are given and compared to simplified approaches.
