B Dark Matter

  1. Jun 14, 2018 #1
    I would like to hear what the opinions are.
    Could sterile neutrino's be dark matter?
    I'm sure this has been discussed if not here then somewhere.

    This depends on the properties of said sterile neutrino. Sterile neutrinos have certainly been discussed as a dark matter candidate, typically with masses around the keV scale. Did you have a particular mass range in mind?

    No not a mass. Was just reading that they may have been found by the Liquid Scintillator Neutrino Detector and it seemed that if they are so hard to detect here on earth then they may be a candidate for Dark Matter.

    So implicitly you are assuming a mass scale, that of the hypothetical sterile suggested as a reason for the LSND anomaly. No, that sterile cannot be dark matter. It has several issues with cosmology. Also note that the LSND experiment is rather old and its results have been known for a long time. Its interpretation in terms of a sterile neutrino is doubtful based on the global experimental status. You may have been alerted by the latest results of MiniBooNE, which are discussed here.
