We report on a search for the pair production of scalar leptoquarks, LQ, using 191 pb⁻¹ of proton-antiproton collision data recorded by the CDF experiment during Run II of the Tevatron. The leptoquarks are sought via their decay into a neutrino and quark yielding missing transverse energy and several jets of large transverse energy. No evidence for leptoquark production is observed, and limits are set on σ(p p→ LQLQ X → ννq q X). Using a next-to-leading order theoretical prediction of the cross section for scalar leptoquark production, we exclude first-generation leptoquarks in the mass interval 78 to 117 GeV/c² at the 95% confidence level for BR(LQ→ νq)=100%.
