Neutrino non-standard interactions meet precision measurements of Neff

A bstract The number of relativistic species, N eff , has been precisely calculated in the standard model, and would be measured to the percent level by CMB-S4 in future. Neutral-current non-standard interactions would affect neutrino decoupling in the early Universe, thus modifying N eff . We param...
