- Аннотация: We study the massless limit in synchrotron radiation and one-photon pair creation in magnetic field. In this limit Schwinger critical field H0 = m2c3/(e) tends to zero, so two characteristic quantum parameters η = H/H0, χ = ηE/mc2 are infinite, and the standard approximations used in analytical calculations fail. Applying Schwinger’s proper time methods we derive simple expressions for synchrotron radiation spectra emitted by massless charges of spins s = 0, 1/2 and the pair creation probability distribution in the quasiclassical (high Landau levels) regime exhibiting simple scaling properties and possessing universal spectral shapes.
