Neutrino non-standard interactions meet precision measurements of N eff
Abstract 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 paramete...
