The influence of strongly magnetized electron-positron plasma on the radiative neutrino transition ν → νγ is investigated. The probability and mean losses of the neutrino energy and momentum are calculated taking account of the photon dispersion and large radiative corrections near the resonance. It is shown that the combined effect of plasma and strong(More)
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(More)
Damping of an electromagnetic wave in a strong magnetic field is analyzed in the kinematic region near the threshold of electron-positron pair production. Damping of the electromagnetic field is shown to be noticeably nonexponential in this region. The resulting width of the photon γ → e+e− decay is considerably smaller than previously known results. PACS(More)
The electromagnetic processes of Compton scattering and photon splitting/merging are investigated in the presence of strongly magnetized electron-positron plasma. The influence of these processes on the radiation transfer in the astrophysical environment is studied. In particular, the contribution of the processes under consideration in coefficients of the(More)
The two-photon two-neutrino interaction induced by magnetic field is investigated. In particular the processes γγ → νν̄ and γ → γνν̄ are studied in the presence of strong magnetic field. An effective Lagrangian and partial amplitudes of the processes are presented. Neutrino emissivities due to the reactions γγ → νν̄ and γ → γνν̄ are calculated taking into(More)
The process of Compton scattering γe → γe in a strongly magnetized medium of arbitrary temperature and zeroth chemical potential was considered. The analytical expressions for the partial cross section in the small concentration limit of the electron-positron plasma are obtained. The numerical estimations for the partial probabilities of this process are(More)
The process of Compton scattering γe → γe in strongly magnetized hot electronpositron plasma is considered. The analytical expressions for the partial cross sections in rarefied plasma are obtained. The numerical estimations of the absorption rates for various scattering channels are presented with taking into account of the photon dispersion and wave(More)
