LHC的意外事件

Accidental matter at the LHC

Luca Di Luzio, Ramona Grober, Jernej F. Kamenik, Marco Nardecchia

摘要:

我们对标准模型的弱尺度扩展进行了分类,这些扩展自动地在可重正化水平上保持其偶然的和近似的对称结构,因此对低能间接探测是不可见的。通过要求有效场论在10^15 GeV尺度下的一致性,并在应用宇宙学约束之后,我们得到了一组有限的可能性,并对其进行了详细分析。这个框架最引人注目的特征之一是存在新的带电和/或有色态,它们可以在高能粒子对撞机中有效地产生,并且在探测器的尺度上是稳定的。

英文摘要:

We classify weak-scale extensions of the Standard Model which automatically preserve its accidental and approximate symmetry structure at the renormalizable level and which are hence invisible to low-energy indirect probes. By requiring the consistency of the effective field theory up to scales of 10^15 GeV and after applying cosmological constraints, we arrive at a finite set of possibilities that we analyze in detail. One of the most striking signatures of this framework is the presence of new charged and/or colored states which can be efficiently produced in high-energy particle colliders and which are stable on the scale of detectors.
