大型强子电子对撞机上的部分子分布和小-x QCD

Parton distributions and small-x QCD at the Large Hadron Electron Collider

Juan Rojo, Fabrizio Caola

摘要:

欧洲核子研究中心(CERN)提议的大型强子电子对撞机(LHeC)将把深度非弹性散射带入未探索的TeV区域。LHeC丰富的物理计划,除其他主题外,包括精确的SM测量,以补充LHC物理以及高能极限下的QCD研究。本文报告了NNPDF框架内正在进行的LHeC CDR研究。我们研究了LHeC模拟数据对PDF不确定性的影响,特别是小x胶子。我们还评估了LHeC的潜力,以解开各种情况下的小x QCD,包括饱和模型和小x remation。最后,我们探讨了如何从DGstrom偏差可以量化包容性的测量。

英文摘要:

The proposed Large Hadron Electron Collider (LHeC) at CERN would bring Deep-Inelastic scattering into the unexplored TeV regime. The LHeC rich physics program, among other topics, includes both precision SM measurements to complement LHC physics as well as studies of QCD in the high energy limit. The present contribution reports on ongoing studies within the NNPDF framework towards the LHeC CDR. We study the impact of LHeC simulated data on PDF uncertainties, in particular the small-x gluon. We also assess the LHeC potential to disentangle between various scenarios of small-x QCD, including saturation models and small-x resummation. Finally, we explore how deviations from DGLAP can be quantified in inclusive measurements.
