Radiation Zeros as an Observable to test Physics beyond the Standard Model

Abstract

The vanishing of the cross section for particular points in phase space - radiation zeros - is examined for the process qqˉW+Wγ q \bar q \to W^+W^- \gamma at high energy. For photon energies that are not too large, the cross section does exhibit deep dips in regions of phase space corresponding to the position of the actual zeros. We show that in these regions the sensitivity to possible anomalous quartic couplings is very large.
