论文摘要
LHC的未来运行为测量质子内两个部分之间的相关性提供了独特的机会，而质子的两个部分从未被检测到。感兴趣的过程是在MUON通道中生产两个带正电荷的W玻璃体腐烂的过程。我们在$ \ sqrt {s} $ = 13 tev上介绍了质子 - 普罗顿碰撞的详细分析，我们将蒙特卡洛事件生成器与我们对parton相关性的计算相结合。我们仔细地将双方散射与相关背景过程进行比较，并追踪通往干净信号样本的路径。构建了几种可观察物，以证明Parton相关性相对于无关散射的清除基准值的影响。我们发现，特别是自旋相关性可能导致我们研究的变量的巨大影响，因为它们与Parton角动量的直接关系，因此是Muon Momenta的方向。我们估计测量值与综合亮度的函数的重要性，并得出结论，LHC有可能在不久的将来检测或在Parton相关性上施加强大的限制。
The future runs of LHC offer a unique opportunity to measure correlations between two partons inside the proton, which have never been experimentally detected. The process of interest is the production of two positively charged W-bosons decaying in the muon channel. We present a detailed analysis of proton-proton collisions at $\sqrt{s}$ = 13 TeV, where we combine Monte Carlo event generators with our calculations of parton correlations. We carefully compare double parton scattering to relevant background processes and trace a path towards a clean signal sample. Several observables are constructed to demonstrate the effect of parton correlations with respect to clear benchmark values for uncorrelated scatterings. We find that especially spin correlations can be responsible for large effects in the variables we study, because of their direct relation with the parton angular momentum and, therefore, the directions of the muon momenta. We estimate the significance of the measurements as a function of the integrated luminosity and conclude that the LHC has the potential to detect, or put strong limits on, parton correlations in the near future.
