Abstract At the Large Hadron Collider (LHC), both the ATLAS and CMS Collaborations have been searching for light charged Higgs bosons via top (anti)quark production and decays channels, like pp → t$$ \overline{t} $$ t ¯ with one top (anti)quark decaying into a charged Higgs boson and a b (anti)quark, when the decay is kinematically open (i.e., when $$ {m}_{H^{\pm }} $$ m H ± ≲ mt). In this paper, we propose new searches at the LHC involving light charged Higgs bosons via their pair production channels like pp → H±h/A and pp → H+H− in the 2-Higgs Doublet Model (2HDM) Type-I and -X scenarios. By focusing on the case where the heavy H state plays the role of the Standard Model (SM)-like Higgs boson with a mass near 125 GeV, we study the aforementioned Higgs boson pair production channels and investigate their bosonic decays, such as H± → W±h and/or H± → W±A. We demonstrate that for a light charged Higgs boson state, with $$ {m}_{H^{\pm }} $$ m H ± ≲ mt, at the LHC, such di-Higgs production and decay channels can give rise to signatures with event rates much larger than those emerging from pp → t$$ \overline{t} $$ t ¯ → t$$ \overline{b} $$ b ¯ H− + c.c. We specifically study h/A → b$$ \overline{b} $$ b ¯ and τ+τ− decays. We, therefore, claim that the discussed combination of new production and decay modes can result in an alternative discovery channel for charged Higgs bosons lighter than the top (anti)quark at the LHC within the above two 2HDM Types. Finally, in order to motivate experimentalists in ATLAS and CMS to search for such signatures, we propose 16 Benchmark Points (BPs) which are compatible with both theoretical and experimental constraints.

Higgs Triplet Model

The characteristic feature of the Higgs Triplet Model (HTM) is the existence of the doubly charged Higgs bosons H±±. In this paper, we study the pair production of doubly charged Higgs bosons in γγ collisions at the International Linear Collider (ILC). We present the production cross-sections and the distributions of the various observables, i.e. the distributions of the transverse momenta, the rapidity distributions for doubly charged Higgs bosons and the production angle distributions of the charged Higgs boson pair. Our numerical results show that, the values of the unpolarized cross-sections can reach a few hundreds of fb. We also study the possible final state for the decay mode H±±→W±W± and relevant Standard Model (SM) background. Due to high produced rate and small SM background, the possible signals of H±± might be detected via this process in the future ILC experiments.

Several theories predict the existence of light doubly charged Higgs bosons (H±±). A search for the pair production of H±± using the DØ detector is described, assuming a 100% branching ratio to muons. In the absence of signal, limits at 95% confidence level, of 118.4 GeV and 98.2 GeV are set for left-handed and right-handed doubly charged Higgs bosons respectively.
