Radiation zeros in weak boson production processes at hadron colliders

Abstract

The Standard Model amplitudes for processes where one or more gauge bosons are emitted exhibit zeros in the angular distributions. The theoretical and experimental aspects of these radiation amplitude zeros are reviewed and some recent results are discussed. In particular, the zeros of the $WZ\gamma$ and $WZZ$ production amplitudes are analyzed. It is briefly explained how radiation zeros can be used to test the SM.Comment: Talk given at 22nd Annual MRST (Montreal-Rochester-Syracuse-Toronto) Meeting: Conference on Theoretical High-Energy Physics, Rochester, New York, 8-9 May 200
