Effects of the R-parity violation in the minimal supersymmetric standard model on dilepton pair production at the CERN LHC

Abstract

We investigate in detail the effects of the R-parity lepton number violation in the minimal supersymmetric standard model (MSSM) on the parent process $pp\to e^{+}{e}^{-}+X$ at the CERN Large Hadron Collider (LHC). The numerical comparisons between the contributions of the R-parity violating effects to the parent process via the Drell-Yan subprocess and the gluon-gluon fusion are made. We find that the R-violating effects on $e^{+}{e}^{-}$ pair production at the LHC could be significant. The results show that the cross section of the $e^{+}{e}^{-}$ pair productions via gluon-gluon collision at the LHC can be of the order of $10^2$ fb, and this subprocess maybe competitive with the production mechanism via the Drell-Yan subprocess. We give also quantitatively the analysis of the effects from both the mass of sneutrino and coupling strength of the R-parity violating interactions.
