DOIAbstract
Submitted to Phys. Lett. B ; see paper for full list of authorsA search for baryon number violation (BNV) in top-quark decays is performed using pp collisions produced by the LHC at sqrt(s)=8 TeV. The top-quark decay considered in this search results in one light lepton (muon or electron), two jets, but no neutrino in the final state. Data used for the analysis were collected by the CMS detector and correspond to an integrated luminosity of 19.5 inverse femtobarns. The event selection is optimized for top quarks produced in pairs, with one having the BNV decay and the other the standard model hadronic decay to three jets. No significant excess of events over the expected yield from standard model processes is observed. The upper limits at 9...
