Descripción
A search is presented for the production of both first- and
second-generation scalar leptoquarks with a final state of either two
electrons and one jet or two muons and one jet. The search is based on a
data sample of proton-proton collisions at center-of-mass energy
√{s }=8 TeV recorded with the CMS detector and corresponding to an
integrated luminosity of 19.6 fb-1 . Upper limits are set on
both the first- and second-generation leptoquark production cross
sections as functions of the leptoquark mass and the leptoquark
couplings to a lepton and a quark. Results are compared with theoretical
predictions to obtain lower limits on the leptoquark mass. At 95%
confidence level, single production of first-generation leptoquarks with
a coupling and branching fraction of 1.0 is excluded for masses below
1730 GeV, and second-generation leptoquarks with a coupling and
branching fraction of 1.0 is excluded for masses below 530 GeV. These
are the best overall limits on the production of first-generation
leptoquarks to date.
