Search for single production of scalar leptoquarks in proton-proton collisions at sqrt(s) = 8 TeV

Understand

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.

• A data sample of proton-proton collisions at center-of-mass energy sqrt(s) = 8 TeV recorded with the CMS detector corresponds to an integrated luminosity of 19.6 inverse femtobarns.
• 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.
