Limits on leptophobic W' after 1 fb^{-1} of LHC data: a lesson on parton level simulations

Abstract

An iso-singlet W' carrying hypercharge one is considered within an effective Lagrangian approach. The predictions for the exclusion in the (M_{W'},g_q/g) parameter space presented in Ref. [1] for the search in the di-jet invariant mass spectrum are shown to be in reasonable agreement with the LHC results based on 1 fb^{-1} of integrated luminosity.
