Dirac Particle in the Presence of a Magnetic Charge in De Sitter Universe: Exact Solutions and Transparency of the Cosmological Horizon
O. V. Veko, E. M. Ovsiyuk and V. M. Red'kov

It has been shown that the monopole background does not affect the transparency properties of the de Sitter cosmological horizon for quantum particles with spin 1/2. One can expect that this conclusion is due only to the geometry of the de Sitter space-time, and it does not depend on spin of the particles.

Key words: magnetic charge, Dirac particle, de Sitter universe, cosmological horizon, exact solution
