Abstract

We present a search for the pair production of first generation scalar leptoquarks (LQ) in data corresponding to an integrated luminosity of 5.4 fb^-1 collected with the D0 detector at the Fermilab Tevatron Collider in pp collisions at √s= 1.96 TeV. In the channel LQLQ → eqv_eq¹, where q, q¹ are u or d quarks, no significant excess of data over background is observed, and we set a 95% C.L. lower limit of 326 GeV on the LQ mass, assuming equal probabilities of LQ decays to eq and v_eq¹.
