The Transitions Γγ → Νν̄ and Γ → Γγ in a Strong Magnetic Field
نویسندگان
چکیده
The photon-neutrino process γγ → ν ¯ ν and photon splitting are considered in a strong magnetic field. The partial polarization amplitudes are calculated within the standard model in the limit of a strong field. The amplitudes do not depend on the field strength in this limit. Using the vector parts of the amplitudes, the process of the photon splitting γ → γγ is investigated both below and above the pair creation threshold. The splitting probabilities are calculated taking account of the photon dispersion and large radiative corrections near the resonance.

A general analysis of the three-vertex loop amplitude in a strong magnetic field, based on the asymptotic form of the electron propagator in the field, is performed. In order to investigate the photonneutrino process γγ → νν̄, the vertex combinations of the scalar– vector–vector (SV V ), pseudoscalar–vector–vector (PV V ), 3–vector (V V V ), and axial-vector–vector–vector (AV V ) types are consi...

متن کاملPhoton splitting above the pair creation threshold in a strong magnetic field
A process of the photon splitting γ → γγ in a strong magnetic field is investigated below and above the pair creation threshold. Contrary to the statement by Baier e.a., the " allowed " channel γ → γ ⊥ γ ⊥ is shown not to be comprehensive for the splitting in the strong field because the " forbidden " channel γ → γ γ ⊥ is also essential. The partial amplitudes and the splitting probabilities ar...
