Model independent reach for W-prime bosons at the LHC
Abstract
The semileptonic decay of single-top-quark production provides a strong probe for W-prime bosons at the CERN Large Hadron Collider. We propose an explicit search strategy for pp -> W-prime -> tb -> l nu b j for use at 7 TeV and 8 TeV collider energies, and integrated luminosities ranging from 5 to 20 fb^-1. Based on detector-simulated results, we predict that a lower bound can be placed on the mass of right-handed W-prime_R with standard model-like couplings of m_{W-prime_R} > 1800 GeV at sqrt{S}=7 TeV with 5 fb^-1, and of m_{W-prime_R} > 2000 GeV at 8 TeV with 20 fb^-1. For left-handed W-prime_L bosons we find a lower bound of 1750-1800 GeV at 7 TeV and 5 fb^-1 depending on the sign of the interference with standard model single-top-quark production. We present effective coupling g^prime dependent limits for accessible masses, and stress the importance of these limits for comparison with theoretical models.
