Title: Search for Lepto-quarks in Dijets Events with Large Transverse Momentum Imbalance Link to paper if available: Session of First Preference: Beyond the Standard Model Session of Second Preference: LP Session: EW physics and beyond II Abstract: We present the results of a search for leptoquark (LQ) pairs using 85.2 pb^-1 of pbarp collider data collected by the DZero experiment at the Fermilab Tevatron from 1994-1996. We observe no evidence for leptoquarks and set limits on sigma (pbarp -> LQ barLQ -> nunu + jets) as a function of the mass of the leptoquark, assuming 100% branching ratio to qnu.
