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...
