Description

We have searched for electrons scattered in the forward direction by neutrinos produced by dumping a 400 GeV/c proton beam on a copper target. We estimate the number of tau neutrinos produced from the decays of Ds mesons in the dump. The data limit the possible magnetic moment of tau neutrinos to be below 5.4x10-7 μB. This rules out the suggestion that tau neutrinos of mass O(MeV) constitute the dark matter in the universe. (orig.)
