Spectral features of primordial gravitational-wave backgrounds can directly reconstruct the mass and decay rate of long-lived BSM particles via the frequencies imprinted by an early matter-dominated epoch.
Adiabatic regularization combined with smoothed transitions suppresses the high-frequency oscillations in the power spectrum of primary gravitational waves about a zero mean.
Kaniadakis entropic cosmology modifies early-universe dynamics and is constrained by its predictions for Starobinsky inflation and the primordial tensor spectrum using current CMB and gravitational-wave observations.
