Query: Search for first generation leptoquark pair production in the electron +
  missing energy + jets final state   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
ppbar collisions at $\sqrt{s}=1.96$ TeV. In the channel $LQ \bar{LQ}
\rightarrow e\nu_e qq'$, where q, q' 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 leptoquark mass, assuming equal probabilities of leptoquark decays
to eq and $\nu_e q'$.
