Familon emission by dense magnetized plasma

Emission of a familon caused by the processes $e^- \to e^- + \phi$, $e^- \to \mu^- + \phi$ in dense magnetized plasma is investigated in the model in which a familon have both direct and no direct coupling to leptons via plasmon. The process probabilities and the integral familon action on plasma are calculated. It is shown that the $P$ odd interference phenomenon in the process $e^- \to \mu^- + \phi$ leads to the familon force acting on plasma along the magnetic field.Comment: 7 pages, LATEX, to appear in Modern Physics Letters
