Some physical properties of SU (2) gauge theories in three dimensions

Physics Letters B 289:1-2 (1992) 115-121

Abstract:

We calculate the string tension and (part of) the glueball mass spectrum for SU (2) lattice gauge theory in three dimensions with the plaquette action. We extrapolate the masses and mass ratios to the continuum limit. We note and comment upon some remarkable similarities and differences between the three- and four-dimensional theories. © 1992.

Bound on the tau neutrino magnetic moment from the BEBC beam dump experiment

Abstract:

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 5.4×10-7 ωB. This rules out the suggestion that tau neutrinos of mass O(MeV) constitute the dark matter in the universe. © 1992.
