Production of leptoquark bosons in ultrahigh-energy neutrino interactions

We consider the resonant production of leptoquark bosons, especially those present in superstring-inspired E6 models, in neutrino-nucleon interactions with E>1 TeV. Such interactions might be probed in proposed large underwater detectors such as DUMAND using atmo- spheric or astrophysical neutrinos. We also compare neutrino-induced production of leptoquark bosons to the e-q fusion process available at ep colliders such as DESY HERA.
