Exotic decays of the Standard Model (SM)-like Higgs boson into beyond-the-SM particles are predicted in a wide range of well-motivated theories. The enormous samples of Higgs bosons that have been and will be produced at the Large Hadron Collider thus constitute one of the key discovery opportunities at that facility, particularly in the upcoming high-statistics, high-luminosity run. Here we review recent theoretical work on models that predict or accommodate exotic Higgs decays, survey the status of current experimental searches, and look forward to future capabilities at dedicated Higgs factories and beyond.

 异国情调的希格斯衰变


在广泛的动机良好的理论中，预测了类似标准模型 （SM） 的希格斯玻色子到超越 SM 粒子的奇异衰变。因此，大型强子对撞机已经和将要产生的大量希格斯玻色子样本构成了该设施的关键发现机会之一，尤其是在即将到来的高统计、高光度运行中。在这里，我们回顾了最近关于预测或适应奇异希格斯衰变的模型的理论工作，调查了当前实验搜索的状态，并展望了希格斯专用工厂及其他地方的未来能力。
