  A preliminary analysis of zero hadronic energy dimuon production in the NuTeV
experiment is presented (nu_mu (anti-nu_mu) + N -> nu_mu(anti-nu_mu) + mu^+ +
mu^- + N). The data show a signal in excess of background which is attributed
to neutrino trident production. This excess is consistent with the Standard
Model prediction including electroweak interference. Other sources of
low-hadronic energy dimuon events are also considered.
