摘要：

Nonminimal composite Higgs scenarios can contain exotic Higgs states which, if observed at the Large Hadron Collider, will help to constrain the underlying UV structure of the strong dynamics. Doubly charged Higgs bosons are well-motivated scalar degrees of freedom in this context. Their phenomenology in typical composite scenarios can differ from well-established Higgs triplet extensions of the SM. Related search strategies are not necessarily adapted to such a scenario as a consequence. In this paper we discuss the sensitivity reach to doubly charged Higgs bosons with decays into pairs of same-sign W bosons. While production cross sections are small, we show that significant constraints on H-+/-+/- -> (WW +/-)-W-+/- can be obtained, providing a new opportunity to constrain the potential composite structure of the TeV scale up to mH(+/-+/-) similar or equal to 800 GeV.
