高能多Higgs产生的唯象研究

A Phenomenological Approach to Multi-Higgs Production at High Energy

Fayez M. Abu-Ajamieh

摘要:

我们解决的问题,在高能量的多希格斯生产的振幅的阶乘增长的基础上发展的希格斯分裂函数和Sudakov因子的唯象方法。我们利用生成泛函的方法来定义几个喷流观测希格斯部门。我们的研究结果表明,纯希格斯分裂应该保留一个良好的UV行为相比,由微扰理论的崩溃和破坏的么正性,由于在阈值或附近产生的粒子的高多重性,这是在标量理论中发现的共同的图片表示。因此,我们认为,多希格斯粒子产生的振幅的阶乘增长的问题可能与微扰理论在一个不再有效的制度中的应用有关,而不是作为新物理学的标志。

英文摘要:

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amplitude of multi-Higgs production is probably associated with applying perturbation theory in a regime where it is no longer valid, as opposed to being a sign of new physics.
