AI总结:

本研究提出以喷注度为重求和变量的MINNLO新公式化表述,完成色单态过程0-喷注度推导,经LHC物理过程验证并与实验及原有方法对比后,拓展至1-喷注度以适配含末态喷注的过程。

摘要:

我们提出了MINNLO方法的一种新公式化表述,以喷注度(jettiness)作为重求和变量,将NNLO量子色动力学(QCD)计算与部分子簇射相匹配。本文从NNLL$^\prime$重求和公式出发,采用0-喷注度给出了色单态过程的完整推导。我们展示了大型强子对撞机(LHC)上Drell-Yan过程与希格斯玻色子产生的唯象结果,并将我们的预言与ATLAS和CMS的数据进行了对比。讨论了与以色单态横动量为重求和变量的原始MINNLO公式表述的差异。我们还进一步将MINNLO预言与GENEVA进行了比较。最后,我们将MINNLO方法的公式化表述拓展至1-喷注度,可应用于末态含一个色单态加一个喷注的过程。

英文摘要:

We present a new formulation of the MINNLO method to match NNLO QCD calculations with parton showers by using jettiness as a resummation variable. The full derivation for colour-singlet processes is presented using $0$-jettiness starting from the NNLL$^\prime$ resummation formula. We show phenomenological results for Drell-Yan and Higgs-boson production at the LHC and compare our predictions to ATLAS and CMS data. Differences to the original MINNLO formulation using the transverse momentum of the colour singlet as resummation variable are discussed. We further present a comparison of MINNLO predictions with GENEVA. Finally, we extend the formulation of the MINNLO method to 1-jettiness which is applicable to processes with a colour singlet plus one jet in the final state.
