论文摘要
从现象学的角度来看，我们提出了对强子山脉处的喷气产生的系统研究，其双重目的是为Parton分布（PDFS）的未来确定提供了理论计算和指导的验证。我们通过将它们包括在全球PDF确定中，并与Electroweak（EW）校正补充的NNLO QCD的理论预测进行比较，从而考虑了7和8 TEV的所有可用的包含喷气和DIJET生产测量。我们评估包含喷气数据之前和之后获得的PDF，特别是Gluon的兼容性。我们比较了单个包含QCD和EW校正，对PDF的影响以及全球拟合质量时的单个式喷气和Dijet可观察到的可观察力。在单一包含的情况下，我们还研究了不同量表选择的作用以及结果在相关实验系统的建模变化时的稳定性。
We present a systematic investigation of jet production at hadron colliders from a phenomenological point of view, with the dual aim of providing a validation of theoretical calculations and guidance to future determinations of parton distributions (PDFs). We account for all available inclusive jet and dijet production measurements from ATLAS and CMS at 7 and 8 TeV by including them in a global PDF determination, and comparing to theoretical predictions at NNLO QCD supplemented by electroweak (EW) corrections. We assess the compatibility of the PDFs, specifically the gluon, obtained before and after inclusion of the jet data. We compare the single-inclusive jet and dijet observables in terms of perturbative behaviour upon inclusion of QCD and EW corrections, impact on the PDFs, and global fit quality. In the single-inclusive case, we also investigate the role played by different scale choices and the stability of the results upon changes in modelling of the correlated experimental systematics.
