Abstract:

A search for pair-production of first generation scalar leptoquarks is performed in the final states containing two electrons and at least two jets or an electron, a neutrino, and at least two jets using proton-proton collision data at

\sqrt{s}=8

TeV. The data were collected by the CMS detector at the LHC, corresponding to an integrated luminosity of 19.6 fb

^{-1}

. First generation scalar leptoquarks with masses less than 1005 (845) GeV are excluded for

\beta = 1(0.5)

, where

\beta

is the branching fraction of a leptoquark to a charged lepton and a quark. These limits are the most stringent limits on first generation leptoquarks to date.

Note:
