AI总结:

本研究计算了质子碰撞中希格斯玻色子加喷注的快度与横动量分布的NLO+NLL精度新预测,推进了$Z$玻色子情形的扩展,指出提升相关固定阶计算精度是满足LHC及FCC能区希格斯与电弱物理可观测量描述精度的必要步骤。

摘要:

我们给出了质子碰撞中伴随喷注的希格斯玻色子发射敏感的快度和横动量分布的新预测,该预测在QCD的NLO(次领头阶)固定阶下计算,并与次领头能量对数精度匹配。我们还重点介绍了将分析扩展到$Z$玻色子情形的首批进展。我们得出的结论是,改进希格斯玻色子和$Z$玻色子加喷注分布的固定阶计算,是在当前LHC能量和标称FCC能量下,达到描述希格斯与电弱物理相关可观测量所需精度水平的必要步骤。

英文摘要:

We present novel predictions for rapidity and transverse-momentum distributions sensitive to the emission of a Higgs boson accompanied by a jet in proton collisions, calculated within the NLO fixed order in QCD and matched with the next-to leading energy-logarithmic accuracy. We also highlight first advancements in the extension of our analysis to the $Z$-boson case. We come out with the message that the improvement of fixed-order calculations on Higgs- and $Z$-boson plus jet distributions is a required step to reach the precision level of the description of observables relevant for Higgs and electroweak physics at current LHC energies and nominal FCC ones.
