LHC和FCC物理学精确QCD硬修正的新方法

New Approach to Hard Corrections in Precision QCD for LHC and FCC Physics

B. F. L. Ward

摘要:

我们提出了一种新的方法来实现硬固定阶修正的预测中探测的过程中的高能碰撞强子束装置,在LHC和未来的FCC设备的一些重点。我们表明,通常的非物理发散的这种修正,因为一个方法的软限制被删除,在我们的方法,使我们将使标准的结果更接近所观察到的排他性分布。我们使用单个Z/γ* 产生和衰变为轻子对作为我们的原型例子,但我们强调,该方法具有普遍适用性。通过这种方式,我们为LHC物理学的理论精度标签的确定开辟了另一条严格基线的道路,并对未来的FCC进行了明显的推广。

英文摘要:

We present a new approach to the realization of hard fixed-order corrections in predictions for the processes probed in high energy colliding hadron beam devices, with some emphasis on the LHC and the future FCC devices. We show that the usual unphysical divergence of such corrections as one approaches the soft limit is removed in our approach, so that we would render the standard results to be closer to the observed exclusive distributions. We use the single Z/γ* production and decay to lepton pairs as our prototypical example, but we stress that the approach has general applicability. In this way, we open another part of the way to rigorous baselines for the determination of the theoretical precision tags for LHC physics, with an obvious generalization to the future FCC as well.
