WW +喷气式飞机生产的次领先订单预测

Next-to-leading order predictions for WW+jet production

John M. Campbell, David J. Miller, Tania Robens

摘要:

在这项工作中,我们报告了一个次领先级计算的WW +喷流生产强子对撞机,随后轻子衰变的W玻色子。单回路贡献的计算是使用广义么正性方法进行的,以便推导出相关振幅的解析表达式。这些振幅已实施的部分子级蒙特卡罗生成器MCFM,我们使用它来提供一个完整的下一个领先的顺序计算。总截面的预测,以及几个关键的观测值的微分分布,计算在14 TeV的大型强子对撞机,以及为未来可能的100 TeV质子-质子对撞机。

英文摘要:

In this work we report on a next-to-leading order calculation of WW + jet production at hadron colliders, with subsequent leptonic decays of the W-bosons included. The calculation of the one-loop contributions is performed using generalized unitarity methods in order to derive analytic expressions for the relevant amplitudes. These amplitudes have been implemented in the parton-level Monte Carlo generator MCFM, which we use to provide a complete next-to-leading order calculation. Predictions for total cross-sections, as well as differential distributions for several key observables, are computed both for the LHC operating at 14 TeV as well as for a possible future 100 TeV proton-proton collider.
