与喷流有关的希格斯玻色子玻色子产生的全阶修正

All-Order Corrections To Higgs Boson Production In Association With Jets

Jeppe R. Andersen

摘要:

我们提出了一个新的框架计算多喷流观测。该框架是基于所有粒子之间的大不变质量的运动学极限中的散射振幅的因式分解。我们表明,通过约束的解析性的散射振幅远离这个限制,我们得到了良好的协议顺序与完整的,固定的顺序微扰计算在低的订单,这些都是可用的,因此得到坚定的预测的所有顺序的行为。作为一个例子,我们研究希格斯玻色子生产通过胶子融合与至少两个喷流在大型强子对撞机。

英文摘要:

We present a new framework for calculating multi-jet observables. The framework is based on the factorisation of scattering amplitudes in the kinematical limit of large invariant mass between all particles. We show that by constraining the analyticity of scattering amplitudes away from this limits, we get good agreement order by order with the full, fixed order perturbative calculation at the low orders where these are available, and therefore get firm predictions on the all-order behaviour. As an example, we study Higgs boson production through gluon fusion in association with at least two jets at the LHC.
