Search for pair-production of first generation scalar leptoquarks in pp collisions at $\sqrt{s}=13~\mathrm{TeV}$ with $2.6~\mathrm{fb}^{-1}$

A search for pair production of first generation scalar leptoquarks is presented, considering a final state containing two electrons and at least two jets, using proton-proton collision data at $\sqrt{s}=13~\mathrm{TeV}$. The data were recorded with the CMS detector at the LHC during 2015, and correspond to an integrated luminosity of $2.6~\mathrm{fb}^{-1}$. First generation scalar leptoquarks with masses less than $1130$ ($920$)$~\mathrm{GeV}$ are excluded for $\beta = 1.0$ ($\beta = 0.5$), where $\beta$ is the branching fraction of a leptoquark decaying to a charged lepton and a quark.
