$$e^+e^-$$ e + e - annihilation on the stochastic background of primordial gravitational waves with BKP18

Abstract The evolution of inflationary primordial gravitational waves with the expansion of the universe is studied while taking into account the $$e^+e^-$$ e + e - annihilation which leads to step correction in the spectrum of primordial gravitational waves which is $$\sim 10\%$$ ∼ 10 % in the ampl...
