Existence of sterile neutrino

  1. Jan 11, 2008 #1
    Because of the existence of sterile neutrino, how and why it gives effect on the big bang nucleosynthesis more than active-active neutrino oscillation. Its a question on behalf of my friend. thanks for any help

    Thats regarding the hypothesis for a light sterile neutrino. Nothing MiniBoone says effects the possibility of say a GUT induced one.

    As for the OPs question. Could you be a little more specific. Obviously an extra neutrino species will change things, sometimes dramatically depending on the model (eg it can cause Leptogenesis)

    But then we are left with no other "verified" sterile neutrinos, which means the original premise of the "existence" of sterile neutrinos in the OP is false.
