Tensor perturbations remain conserved on super-horizon scales when radiation initial conditions during reheating are locally perturbed by existing modes, unlike global equilibrium assumptions that suppress amplitudes.

A Z4 × Z3 discrete gauge symmetry in the SM requires three new Majorana fermions whose lightest member is stable DM with mass from a singlet scalar VEV near the electroweak scale, enabling WIMP freeze-out via scalar-mediated annihilation.
Polynomial α-attractor P-models of inflation accommodate Planck and Planck+ACT CMB data for ranges of reheating temperatures when decays and fragmentation are included.
Double beta decay experiments can constrain couplings of sub-MeV Majoron-like scalars to neutrinos at |a_ν| ≈ 2×10^{-6} through on- and off-shell production effects on the electron spectrum.
