Findings

Potential to identify fermionic leptoquarks via b-jet plus same-sign dileptons

Existing LHC data may contain undiscovered signals of exotic quarks

Analysis can constrain or support the 3-3-1 model parameters

Abstract

Within the 3-3-1 model framework, we consider the production and decay of fermionic leptoquarks into a striking experimental signature at the LHC: a narrow resonance at the $b$ jet plus same-sign dileptons channel. The data already accumulated by the LHC collaborations may hide a large number of events associated to the production and decay of such exotic quarks, allowing one to investigate large portions of the parameters space of the model. The observation or not of such events would shed light on the construction of models presenting heavy exotic quarks.
