Field-induced axion decay $a\to e^{+}{e}^{-}$ in plasma

Abstract

The axion decay $a\to e^{+}{e}^{-}$ is investigated in the presence of a plasma and an external magnetic field. The results demonstrate a strong catalyzing influence of medium. The axion lifetime in the magnetic field of order $10^{15}$ G and at the temperature of order 10 MeV is reduced to $10^4$ s.
