Phys. Rev. D 67, 073018 (2003) [5 pages]Optical activity of neutrinos and antineutrinosReceived 5 March 2003; published 25 April 2003 Using the one-loop helicity amplitudes for low-energy νγ⃗νγ and ν̅ γ⃗ν̅ γ scattering in the standard model with massless neutrinos, we study the optical activity of a sea of neutrinos and antineutrinos. In particular, we estimate the values of the index of refraction and rotary power of this medium in the absence of dispersion. © 2003 The American Physical Society URL:
