Abstract: | The effect of a strongly magnetized cold plasma on the Compton-like photoproduction of a neutrino on an electron \(\gamma e \to e\nu \bar \nu \) has been considered. The contribution of this process to the neutrino emissivity has been calculated with the inclusion of the dispersion properties of a photon in the medium. A method for the calculation of the emissivity of the process under consideration in terms of the width of the Compton absorption of the photon has been proposed. This method shows that the neutrino emissivity owing to the \(\gamma e \to e\nu \bar \nu \) reaction is significantly modified as compared to the previously reported data. |
