A new scheme for the neutrino collision term valid from light to heavy mediator regimes, with smooth transition as the universe cools, for scalar-mediated NSI in Dirac and Majorana cases.
Reanalysis of DESI full-shape clustering data tightens constraints on neutrino mass, spatial curvature, and dark energy equation-of-state parameters relative to BAO-only results.
Fisher forecasts indicate that Lyα-21cm cross-spectra with PUMA and CMB data can improve constraints on neutrino self-interaction strength G_eff by 1-2 orders of magnitude over CMB alone.
