共振双光子现象学的简化

Resonant Diphoton Phenomenology Simplified

Giuliano Panico, Luca Vecchi, Andrea Wulzer

摘要:

本文提出了一个描述强子对撞机共振双光子现象的框架。它可以用于一个全面的模型独立的解释实验数据。在一般的框架内,很少有基准场景被定义为代表的各种现象学的选择和/或动机的新的物理场景。他们的使用说明进行表征的750 GeV过剩,根据现有的实验结果重铸。我们还进行了评估的共振的属性可以推断,发现后,通过仔细的实验研究的双光子分布。这些包括新粒子的自旋J及其主导的生产模式。还可以获得关于其CP奇偶校验的部分信息,但仅针对$J\geq2$。共振CP属性的完整测定需要研究伴随共振双光子产生的初始状态辐射的模式。

英文摘要:

A framework is proposed to describe resonant diphoton phenomenology at hadron colliders in full generality. It can be employed for a comprehensive model-independent interpretation of the experimental data. Within the general framework, few benchmark scenarios are defined as representative of the various phenomenological options and/or of motivated new physics scenarios. Their usage is illustrated by performing a characterization of the 750 GeV excess, based on a recast of available experimental results. We also perform an assessment of which properties of the resonance could be inferred, after discovery, by a careful experimental study of the diphoton distributions. These include the spin J of the new particle and its dominant production mode. Partial information on its CP-parity can also be obtained, but only for $J\geq2$. The complete determination of the resonance CP properties requires studying the pattern of the initial state radiation that accompanies the resonant diphoton production.
