The power spectrum is calculated from the linear density perturbations solving the Vlasov-Poisson system
Vlasov-Poisson system is a set of diff.eqn. in which all matter-radiation species are coupled

Suppression of the power spectrum, at first order depends on energy density ratios
CMB angular spectrum and matter power spectrum are both dependent on neutrino mass, N_eff and ordering
