本报告的目的是总结目前的情况，并讨论可能的搜索策略，在LHC的标准模型的非超对称扩展的带电标量。这样的标量出现在多希格斯-双重模型中，特别是在流行的双希格斯-双重模型中，允许带电和额外的中性希格斯玻色子。这些模型有吸引力的性质，电弱精密可观测量自动在树级与标准模型一致。对于这个框架最流行的版本，模型II，带电希格斯玻色子的发现仍然具有挑战性，因为参数空间变得非常有限，QCD背景非常高。我们还简要评论暗物质的模型，约束相应的带电标量发生在这些模型。可能发现扩展标量扇区的风险是非常高的，这些搜索应该在所有可能的渠道中进行，在LHC和未来的对撞机上。

The goal of this report is to summarize the current situation and discuss possible search strategies for charged scalars, in non-supersymmetric extensions of the Standard Model at the LHC. Such scalars appear in Multi-Higgs-Doublet models, in particular in the popular Two-Higgs-Doublet model, allowing for charged and additional neutral Higgs bosons. These models have the attractive property that electroweak precision observables are automatically in agreement with the Standard Model at the tree level. For the most popular version of this framework, Model II, a discovery of a charged Higgs boson remains challenging, since the parameter space is becoming very constrained, and the QCD background is very high. We also briefly comment on models with dark matter which constrain the corresponding charged scalars that occur in these models. The stakes of a possible discovery of an extended scalar sector are very high, and these searches should be pursued in all conceivable channels, at the LHC and at future colliders.
