标题： Scalar radiation zeros at the LHC

摘要： 我们考虑粒子物理标准模型的一类单态标量扩展，其中标量仅与非定域状态耦合。 因此，涉及单态标量的低阶树图过程消失，提供了一种独特的现象学，可能允许逃避对新单态标量场的现有约束。 我们描述了在大型强子对撞机上搜索此类状态的策略，并确定未来可以探索的参数空间。 显示英文摘要

摘要： We consider a class of singlet scalar extensions of the Standard Model of particle physics in which the scalar couples only to off-shell states. As a result, low-order tree-level processes involving the singlet scalar vanish, providing a unique phenomenology that may allow to evade existing constraints on new singlet scalar fields. We describe search strategies for such states at the Large Hadron Collider and identify the parameter space that can be explored in the future.
