Phys. Rev. D 59, 013012 (1998) [6 pages]High energy photon-neutrino interactionsReceived 17 July 1998; published 8 December 1998 A general decomposition of the amplitudes for the 2⃗2 processes γν⃗γν and γγ⃗νν̅ is obtained using gauge invariance and Bose symmetry. The restrictions implied by this decomposition are investigated for the reaction γγ⃗νν̅ by computing the one-loop helicity amplitudes in the standard model. In the center of mass, where √s=2ω, the cross section grows roughly as ω6 up to the threshold for W-boson production, √s=2mW. Astrophysical implications of very high energy photon-neutrino interactions are discussed. © 1998 The American Physical Society URL:
