Abstract
We present the results of a search for pair production of first-generation
scalar leptoquarks (LQ) in the final state arising from LQLQ -> eqeq using
1.1 pb^{-1} of pp collisions at sqrt{s} = 7 TeV collected with the CMS
detector at the CERN LHC. The number of observed events is in good
agreement with the predictions for standard model background processes,
and we consequently set an upper limit on the LQ cross section times
beta^2 as a function of the LQ mass, where beta is the branching fraction
of LQ -> eq. We set a 95% C.L. lower limit on the mass of a
first-generation scalar LQ at 220 GeV/c^2 for beta = 1.
