The Vavilov-Cherenkov radiation by relict photon gas

Abstract

Based on the new quantum Vavilov-Cherenkov,s radiation(VCR) theory (PRL,2004),it is stated the possibility of threshold realization in the modern epoch of the novel VCR effect by the relict photon gas, when it is traversed by relativistic particles of the cosmic rays with \gamma \geq \gamma_th \cong 2 \cdot 10^10, where \gamma^2 = 1 - \frac{V^2}{C^2}, v is the speed of particles, and c is the speed of the light in vacuum.
