论文摘要
我们在LHC的领先顺序准确性和结合了QCD辐射的效果之后，研究了LHC在LHC处的双方散射（DPS）对四射流产生的贡献。除DPS外，我们还包括并讨论了单个Parton散射（SP）的贡献。我们发现QCD辐射对理论预测产生了重大影响，而DPS的贡献比SPS更大。我们还研究了许多可观察到的有关DPS和SPS事件歧视的有效性，并提出了运动型削减，以改善测量四射流生产中DPS的前景。
We study the contribution from double parton scattering (DPS) to four-jet production at the LHC, both at the leading order accuracy and after incorporating the effects of QCD radiation. Apart from DPS, we also include and discuss the contribution from single parton scattering (SPS). We find that the QCD radiation impacts theoretical predictions significantly, with DPS contributions more affected than the SPS. We also examine a number of observables in regard to their effectiveness for discrimination between DPS and SPS events and propose sets of kinematical cuts to improve the prospects of measuring DPS in four-jet production.
