Evidence for Diffractive Charm Production in numu Fe and nubarmu Fe Scattering at the Tevatron
Abstract
We present evidence for the diffractive processes numu Fe -> mu- Ds+ (Ds*+) Fe and nubarmu Fe -> mu+ Ds- (Ds*-) Fe using the Fermilab SSQT neutrino beam and the Lab E neutrino detector. We observe the neutrino trident reactions numu Fe -> numu mu- mu+ Fe and nubarmu Fe -> nubarmu mu+ mu- Fe at rates consistent with Standard Model expectations. We see no evidence for neutral-current production of J/psi via either diffractive or deep inelastic scattering mechanisms.
