We report on a search for the pair production of scalar leptoquarks (LQ), using 191pb-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 LQ production is observed, and limits are set on σ(pp̄→LQLQ̄X→νν̄qq̄X). Using a next-to-leading order theoretical prediction of the cross section for LQ production, we exclude first-generation LQ in the mass interval 78 to 117GeV/c2 at the 95% confidence level for BR(LQ→νq)=100%. © 2005 The American Physical Society.
