Anna Kulesza, W. James Stirling (University of Durham)
TL;DR
This paper proposes using like-sign W boson pair production at the LHC as a clean method to detect and study double parton scattering, which is important for understanding backgrounds in new physics searches.
Contribution
It introduces like-sign W pair production as a novel, clean probe for double parton scattering at the LHC, aiding in background calibration.
Findings
Like-sign W pair production is a promising signature for double parton scattering.
This method can help calibrate double parton scattering backgrounds for new physics searches.
The approach offers a cleaner signal compared to other processes.
Abstract
Double parton scattering, i.e. two parton hard scattering processes in the same hadron-hadron collision, may constitute an important background for Higgs and other new particle searches at the LHC. We point out that like-sign W pair production provides a relatively clean way of searching for, and calibrating, double parton scattering at the LHC.
