Abstract

In this paper we study events with W + jets final state, produced in double parton (DP) interactions, as a background to the associated Higgs boson (H) and W production, with \( H \to b\bar{b} \) decay, at the Tevatron. We have found that the event yield from the DP background can be quite sizable, which necessitates a choice of selection criteria to separate the HW and DP production processes. We suggest a set of variables sensitive to the kinematics of DP and HW events. We show that these variables, being used as an input to the artificial neural network, allow one to significantly improve a sensitivity to the Higgs boson production.
