Photon 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...

Pair creation by a photon in a strong magnetic field

The process of pair creation by a photon in a strong magnetic field is investigated basing on the polarization operator in the field. The total probability of the process is found in a relatively simple form. The probability exhibits a ”saw-tooth” pattern because of divergences arising when the electron and positron are created at threshold of the Landau energy levels. The pattern will be washe...

Photon Splitting and Pair Conversion in Strong Magnetic Fields

The magnetospheres of neutron stars provide a valuable testing ground for as-yet unverified theoretical predictions of quantum electrodynamics (QED) in strong electromagnetic fields. Exhibiting magnetic field strengths well in excess of a TeraGauss, such compact astrophysical environments permit the action of exotic mechanisms that are forbidden by symmetries in field-free regions. Foremost amo...

Photon Splitting in a Very Strong Magnetic Field.

Photon splitting in a very strong magnetic field is analyzed for energy ω < 2m. The amplitude obtained on the base of operator-diagram technique is used. It is shown that in a magnetic field much higher than critical one the splitting amplitude is independent on the field. Our calculation is in a good agreement with previous results of Adler and in a strong contradiction with recent paper of Me...

Photon-pair conversion into neutrinos in a strong magnetic field

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...
