Revisiting scalar leptoquark at the LHC

Understand

We investigate the Standard Model (SM) extended with a colored charged scalar, leptoquark, having fractional electromagnetic charge $-1/3$.

• We mostly focus on the decays of the leptoquark into second and third generations via $c\,\mu, t\, \tau$ decay modes.
• We perform a PYTHIA-based simulation considering all the dominant SM backgrounds at the LHC with 14\,TeV center of mass energy.
• Limits have been calculated for the leptoquark mass that can be probed at the LHC with an integrated luminosity of 3000 fb$^{-1}$.
