Abstract
Within the standardSU(2)×U(1) model differential cross sections and angular distributions of all polarization states are studied for all channels of gauge vector boson pairs accessible in hadron hadron collisions,W+W−,Z0Z0,Zγ,ZW, γW. The zero in the unpolarized angular distribution ofq\(\bar q\)→Wγ reported theoretically by Mikaelian et al. [1] is confirmed. The origin of this zero is studied which was discovered by Brown, Mikaelian, Samuel, and Shadev. None of the other channels exhibits a zero in the unpolarized angular distribution, but strong minima at cosΘ=0 are predicted for\(q_i \bar q_j \to Z\gamma \) and\(q_i \bar q_j \to ZW^ + \). These are of different origin than the Mikaelian zero. Simple structure functions suggest that these minima are seen inp\(\bar p\) collisions.
