Primordial gravitational waves predictions for GW170817-compatible Einstein–Gauss–Bonnet theory

In this work we shall calculate in detail the effect of an GW170817-compatible Einstein-Gauss-Bonnet theory on energy spectrum primordial gravitational waves. The is affected by two characteristics, overall amplification/damping factor caused and tensor spectral index tensor-to-scalar ratio. We present formalism for studying inflationary dynamics post-inflationary theories all redshifts starting from radiation era up to dark era. exemplify our using characteristic models, which produce viable eras. As demonstrate, remarkably damping/amplification order unity, thus models affect waves only via their Both have a blue tilted spectrum, therefore predicted gravity can be detectable most future experiments, various reheating temperatures.
