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.

Abstract A search for charged Higgs bosons decaying into W±W± or W±Z bosons is performed, involving experimental signatures with two leptons of the same charge, or three or four leptons with a variety of charge combinations, missing transverse momentum and jets. A data sample of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider between 2015 and 2018 is used. The data correspond to a total integrated luminosity of 139 fb−1. The search is guided by a type-II seesaw model that extends the scalar sector of the Standard Model with a scalar triplet, leading to a phenomenology that includes doubly and singly charged Higgs bosons. Two scenarios are explored, corresponding to the pair production of doubly charged H±± bosons, or the associated production of a doubly charged H±± boson and a singly charged H± boson. No significant deviations from the Standard Model predictions are observed. H±± bosons are excluded at 95% confidence level up to 350 GeV and 230 GeV for the pair and associated production modes, respectively.
