Resumen:
This paper describes searches for the pair production of first or second
generation scalar leptoquarks using 35/pb of proton-proton collision
data recorded by the ATLAS detector at sqrt(s)=7 TeV. Leptoquarks are
seached in events with two oppositely charged muons or electrons and at
least two jets, and in events with one muon or electron, missing
transverse momentum and at least two jets. After event selection, the
observed yields are consistent with the predicted backgrounds.
Leptoquark production is excluded at the 95% CL for masses mLQ<376
(319) GeV and mLQ<422 (362) GeV for first and second generation
scalar leptoquarks, respectively, when assuming the branching fraction
of a leptoquark to a charged lepton is equal to 1.0 (0.5).
