粒子物理学的标准模型是一个非常成功的基本相互作用理论，但它有许多已知的局限性。因此，它被广泛认为是一种描述TeV尺度附近相互作用的有效场论。存在过多的策略来扩展标准模型，其中许多包含新粒子或动力学的预测，这些粒子或动力学可能在大型强子对撞机（LHC）的质子-质子碰撞中表现出来。到目前为止，还没有观察到任何一个，并且大部分用于解决悬而未决问题的自然解决方案的可用相空间都被排除在外。如果新的物理学存在，那么它要么是重的（即在当前搜索的范围之外），要么是隐藏的（即当前与标准模型背景无法区分）。我们总结了现有的搜索，并讨论未来的方向在大型强子对撞机。
The standard model of particle physics is an extremely successful theory of fundamental interactions, but it has many known limitations. It is therefore widely believed to be an effective field theory that describes interactions near the TeV scale. A plethora of strategies exist to extend the standard model, many of which contain predictions of new particles or dynamics that could manifest in proton-proton collisions at the Large Hadron Collider (LHC). As of now, none have been observed, and much of the available phase space for natural solutions to outstanding problems is excluded. If new physics exists, it is therefore either heavy (i.e. above the reach of current searches) or hidden (i.e. currently indistinguishable from standard model backgrounds). We summarize the existing searches, and discuss future directions at the LHC.
