Productions of heavy charged leptons via gluon fusion at LHC: A revisit

Understand

Heavy charged lepton productions via gluon fusion at the LHC are revisited.

• Full loop calculations are adopted with an updated parton distribution function and electroweak data.
• Including contribution from new generation quarks in the loop, pair production of the sequential heavy lepton via gluon fusion at the LHC dominates over that via the Drell-Yan mechanism in some heavy lepton mass range.
• Exotic lepton single production of vector-like lepton extended models is also calculated.
