FOURTH GENERATION LEPTONS SEARCH IN γγ → ℓ-ℓ+ PROCESS AT THE CERN-LHC

Abstract

The pp → pXp production is known to be one of the cleanest channels at the Large Hadron Collider (LHC). In this work, we investigate the potential of the exclusive pp → pℓ-ℓ+p process to probe fourth family leptons via anomalous interactions at the LHC by considering three forward detector acceptances: 0.0015 < ξ < 0.5, 0.0015 < ξ <0 .15, and 0.1 < ξ < 0.5. The sensitivity of the model parameters have been obtained at the 95% confidence level.
