Abstract

We present the results of a search for leptoquark (LQ) pairs in (85.2 ± 3.7) pb^-1 of pp̅ collider data collected by the D0 experiment at the Fermilab Tevatron. We observe no evidence for leptoquark production and set a limit on σ(pp̅→ LQ L̅Q̅→ νν + jets) as a function of the mass of the leptoquark (m_LQ). Assuming the decay LQ → νq, we exclude scalar leptoquarks for m_LQ< 98 GeV/c², and vector leptoquarks for m_LQ < 200 GeV/c² and coupling which produces the minimum cross section, at a 95% confidence level.
