在Tevatron上作为相关HW产生背景的双部分子相互作用

Double parton interactions as a background to associated HW production at the Tevatron

Dmitry Bandurin, Georgy Golovanov, Nikolai Skachkov

摘要:

本文研究了在Tevatron上,在双部分子(DP)相互作用中产生的W ~+喷流末态事件,作为相关的希格斯玻色子(H)和W产生的背景,H->bbar衰变。我们已经发现,从DP背景的事件产量可以是相当可观的,这需要选择的选择标准,以分开HW和DP生产过程。我们提出了一组敏感的DP和HW事件的运动学变量。我们表明,这些变量,被用作人工神经网络的输入,允许显着提高灵敏度的希格斯玻色子生产。

英文摘要:

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->bbar 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.
