本文提出民主3HDM中b夸克伴随产生可探测反上夸克型希格斯，现有LHC搜索最灵敏，未来对撞机可扩展参数空间探测。
AI 中文摘要
我们证明存在一个理论上动机良好的希格斯扇区，其中传统的重希格斯产生机制被抑制。在此极限下，b夸克伴随产生通道成为主要产生机制。我们论证了民主三希格斯二重态模型（3HDM）提供了一个可行的超出标准模型（BSM）框架，在该框架中可以实现此极限。我们进一步表明，现有的b夸克伴随搜索提供了对此3HDM场景在反上夸克型极限下最灵敏的大型强子对撞机（LHC）探针，并推导出对其参数空间的相应约束。我们还提出了未来对撞机搜索的展望，展示了它们进一步探测该模型反上夸克型参数空间的潜力。
英文摘要
We show that there exists a theoretically well-motivated Higgs sector in which the conventional heavy-Higgs production mechanisms are suppressed. In this limit, the $b$-associated production channel assumes the role of the primary production mechanism. We demonstrate that the democratic three Higgs-doublet model (3HDM) provides a viable beyond the SM (BSM) framework in which this limit can be realized. We further show that existing $b$-associated searches provide the most sensitive LHC probe of this 3HDM scenario in the up-phobic limit and derive the corresponding constraints on its parameter space. We also present projections for future collider searches, demonstrating their potential to probe further regions of the model's up-phobic parameter space.
