论文摘要
我们通过基于Higgs分裂功能和Sudakov因素开发现象学方法来解决高能生产幅度的阶乘增长问题。我们利用生成函数的方法来定义希格斯扇区的几个Jet可观测值。我们的结果表明，与扰动理论的分解和由于在阈值或接近阈值附近产生的粒子高度多样性所致（在标量理论中发现的高度多样性）相比，纯Higgs分裂应保留良好的紫外线行为。因此，我们认为，多基格斯生产幅度的阶乘增长问题可能与在不再有效的政权中应用扰动理论有关，而不是成为新物理学的标志。
We tackle the issue of the factorial growth in the amplitudes of multi-Higgs production at high energy by developing a phenomenological approach based on the Higgs splitting functions and Sudakov factors. We utilize the method of generating functionals to define several jet observables for the Higgs sector. Our results suggest that pure Higgs splittings should retain a good UV behavior in contrast to the common picture represented by the breakdown of perturbation theory and violation of unitarity due to the high multiplicity of particles produced at or near threshold, which is found in scalar theories. We thus argue that the issue of the factorial growth in the amplitude of multi-Higgs production is probably associated with applying perturbation theory in a regime where it is no longer valid, as opposed to being a sign of new physics.
