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.

Higgs Triplet Model

The singly and doubly charged Higgs bosons (H± and H±±) are the typical particles predicted in the Higgs Triplet Model and the observation of these particles can be regarded as the direct evidence of new physics. In this paper, we focus on the study of the singly and doubly charged Higgs bosons associated production process: e+e- → H+H--W+. We present the production cross sections and the distributions of the transverse momenta and the rapidity distributions for outgoing particles. The numerical results show that the production rates can reach the level of several fb with reasonable parameter values. So, one can expect that enough signals could be produced in the future high-energy e+e- collider experiments. The relevant SM backgrounds are also discussed in the case that the vacuum expectation value of the triplet is around 1 GeV.

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.
