title: Pair production by a circularly polarized electromagnetic wave in a plasma.
abstract: We present the results of the calculation of the electron-positron pair creation probability by a circularly polarized electromagnetic wave during its propagation in underdense collisionless plasmas. The dependence of the probability on the frequency and the amplitude of the pulse is studied in detail.
