Abstract: (Elsevier)

We calculate the contribution of an electric dipole ZZγ transition to the e + e − →ν ν γ cross section. With suitable cuts in the photon spectrum, it should be possible to improve, by two orders of magnitude, the present bound on the coupling constant.

Note:

Revised version

electron positron: annihilation
neutrino: pair production
cross section: energy dependence
vertex function: (2Z0 photon)
neutrino: flavor
Z0: electric moment
transition: dipole
CP: violation
Z0: composite
