Search for pair production of first-generation scalar leptoquarks at √s=13 TeV
A search for the pair production of first-generation scalar leptoquarks is performed using proton-proton collision data recorded at 13 TeV center-of-mass energy with the CMS detector at the LHC. The data correspond to an integrated luminosity of 35.9 fb−1. The leptoquarks are assumed to decay prom...

| description | A search for the pair production of first-generation scalar leptoquarks is performed using proton-proton
collision data recorded at 13 TeV center-of-mass energy with the CMS detector at the LHC. The data
correspond to an integrated luminosity of 35.9 fb−1. The leptoquarks are assumed to decay promptly to a
quark and either an electron or a neutrino, with branching fractions β and 1 − β, respectively. The search
targets the decay final states comprising two electrons, or one electron and large missing transverse
momentum, along with two quarks that are detected as hadronic jets. First-generation scalar leptoquarks
with masses below 1435 (1270) GeV are excluded for β ¼ 1.0ð0.5Þ. These are the most stringent limits on
the mass of first-generation scalar leptoquarks to date. The data are also interpreted to set exclusion limits in
the context of an R-parity violating supersymmetric model, predicting promptly decaying top squarks with
a similar dielectron final state. |
