LHC Sensitivity to Wbb Production via Double Parton Scattering
Abstract
We investigate the potential to observe double parton scattering at the Large Hadron Collider in pp -> W bb X -> mu nu bb X at 7 TeV. Our analysis tests the efficacy of several kinematic variables in isolating the double parton process of interest from the single parton process and relevant backgrounds for the first 10/fb of integrated luminosity. These variables are constructed to expose the independent nature of the two subprocesses in double parton scattering, pp -> mu nu and pp -> bb X. We use next-to-leading order perturbative predictions for the double parton and single parton scattering components of W bb and for the pertinent backgrounds. The next-to-leading order contributions are important for a proper description of some of the observables we compute. We find that the double parton process can be identified and measured with significance ~ 10, provided the double parton scattering effective cross section ~ 12 mb.
