Phys. Rev. Lett. 79, 569–571 (1997)Photon-Neutrino InteractionsReceived 27 February 1997; published in the issue dated 28 July 1997 The cross sections for the processes γν→γγν, γγ→γνν̅ , and νν̅ →γγγ are calculated with the aid of an effective Lagrangian derived from the standard model. These cross sections are shown to be much larger than the elastic cross section σ(γν→γν) for photon energies ω>1keV. Possible astrophysical implications are discussed. © 1997 The American Physical Society URL:
