Available in PDF, EPUB and Kindle. Book excerpt: We report on a search for pair production of first-generation scalar leptoquarks (LQ) in pp collisions at √(s)=1.96 TeV using an integrated luminosity of 203 pb−1 collected at the Fermilab Tevatron collider by the CDF experiment. We observe no evidence for LQ production in the topologies arising from LQLQ→eqeq and LQLQ→eq?q, and derive 95% C.L. upper limits on the LQ production cross section. The results are combined with those obtained from a separately reported CDF search in the topology arising from LQLQ→?q?q and 95% C.L. lower limits on the LQ mass as a function of ?=BR(LQ→eq) are derived. The limits are 236, 205 and 145 GeV/c2 for ?=1, ?=0.5 and ?=0.1, respectively.
