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

TL;DR

This paper examines the constraints on a hypothetical leptophobic W' boson using LHC data, highlighting the importance of parton-level simulations in interpreting experimental exclusions.

Contribution

It provides a detailed analysis of W' exclusion limits within an effective Lagrangian framework, emphasizing lessons learned from parton-level simulation approaches.

Findings

LHC data constrains W' mass and coupling parameters

Parton-level simulations align with experimental exclusion results

Effective Lagrangian approach clarifies W' search sensitivities

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.
