双峰：超越狭义相对论的共振产生的可能信号
Twin Peaks: A possible signal in the production of resonances beyond special relativity
摘要：
人们通常认为量子引力修正会以某种方式改变狭义相对论的对称性。在本文中，我们指出，在变形相对论理论的框架内，不排除对狭义相对论进行非常低能量（相对于普朗克能量）的修正的可能性，而且，根据该尺度的值，这种可能性可以在加速器物理学中得到检验。特别地，我们从文献中选取了一个超越狭义相对论的相对论运动学的简单例子，并得到了一个显著的效果：两个相关峰（“双峰”）与一个共振相关联。我们详细分析了这种现象，使用LEP数据，把限制的TeV的顺序上的规模的修正狭义相对论，并注意到，这样的效果可能会观察到在未来的非常高的能量质子对撞机。
英文摘要：
It is usually expected that quantum gravity corrections will modify somehow the symmetries of special relativity. In this paper we point out that the possibility of very low-energy (with respect to the Planck energy) modifications to special relativity in the framework of a deformed relativistic theory is not ruled out, and that, depending on the value of that scale, such a possibility could be tested in accelerator physics. In particular, we take a simple example of a relativistic kinematics beyond special relativity from the literature, and obtain a remarkable effect: two correlated peaks ("twin peaks") associated to a single resonance. We analyze this phenomenology in detail, use LEP data to put constraints of the order of TeV on the scale of corrections to special relativity, and note that such an effect might be observable in a future very high-energy proton collider.
