“…The charged sector of a theory with scalar triplet(s) is very interesting due to the tree-level interactions h ± i −W ∓ − Z for Y = 0, ±2 hypercharge triplets which break the custodial symmetry [7,[13][14][15]. In the TNMSSM this coupling is given by 5) where the rotation angles are defined in Eq.…”

We investigate an extension of the Minimal Supersymmetric Standard Model (MSSM) containing a SU(2) Higgs triplet of zero hypercharge and a gauge singlet. We focus on a scenario of this model which allows a light pseudoscalar and/or a scalar below 100 GeV in the spectrum, consistent with the most recent data from the LHC and the earlier data from the LEP experiments. The triplet extension gives rise to two additional charged Higgs bosons which do not couple to fermions but can decay into ZW ± . The presence of a very light pseduoscalar opens a 1 W ± decay mode for the light charged Higgs boson just like Z 3 symmetric singlet-extension (NMSSM). A triplet type charged Higgs can be produced via vector boson fusion at the tree-level which is absent in 2HDM and MSSM and NMSSM. If such charged Higgs boson is pair produced both ZW ± and a 1 W ± decay modes can be probed which can prove the existence of triplet and singlet both.

“…Another dynamical way to generate a µ D term is by adding a SM gauge singlet superfield to the spectrum [26][27][28][29][30], as in the NMSSM. Thus a triplet-singlet extended supersymmetric SM built on the superpotential of the MSSM, can address both the fine tuning issue and resolve, at the same time, the problem of the µ-term of the two Higgs doublets [48][49][50][51][52][53].…”

We investigate a supersymmetric extension of the Minimal Supersymmetric Standard Model (MSSM), called the TNMSSM, containing a SU(2) Higgs triplet (T ) of Y = 0 hypercharge and a singlet superfields (Ŝ) in the corresponding superpotential. The model can be viewed, equivalently, as an extension of the NMSSM with the addition of â T −Ŝ interaction and of an extra coupling of the triplet to the two Higgs doublets of the NMSSM. In this scenario the Higgs particle spectrum at tree-level gets additional mass contributions from the triplet and singlet scalar components respect to the MSSM, which are particularly enhanced at low tan β. We calculate the one-loop Higgs masses for the neutral physical Higgs bosons by a Coleman-Weinberg effective potential approach. In particular, we investigate separately the impact of the radiative corrections due to the electroweak, gauge-gaugino-higgsino, fermion-sfermion and Higgs self-interactions to the Higgs masses. Due to the larger number of scalars and of triplet and singlet couplings, the Higgs corrections can be larger than the strong corrections. This reduces the amount of fine-tuning required to fit the recent Higgs data. Using the expressions of the beta-functions of the model, we show that the large triplet singlet coupling remains perturbative up to ∼ 10 8−10 GeV. The model is also characterized by a light pseudoscalar in the spectrum, which is a linear combination of the triplet, doublet and singlet CP-odd components. We discuss the production and decay signatures of the Higgs bosons in this model, including scenarios with hidden Higgses, which could be investigated at the LHC in the current run.

“…The vev of the Y = 0 triplet, which breaks the custodial symmetry, is then restricted to 5 GeV [5,6]. Breaking of custodial symmetry leads to the non-standard signature of h ± → ZW ± which is very typical of triplet extension [5,6].…”

Extending the Standard Model (SM) scalar sector via one or multiple Higgs field(s) in higher representation brings one or more charged Higgs bosons in the spectrum. Some of these gauge representations with appropriate hypercharge can bring up doubly charged Higgs boson and can be easily distinguished from the existing models with only singly charged Higgs boson. In this study we focus on distinguishing the singly charged Higgs bosons from different representations, viz. doublets and triplets of SU (2) L gauge group. We consider a supersymmetric extension of SM with a gauge singlet and SU (2) L triplet with Y = 0 as a benchmark scenario with the possibility of rich phenomenology due to existence of light pseudoscalar for Z 3 symmetric superpotential. A detailed collider simulation considering all the SM backgrounds has been carried out in order to classify the final states which are favourable to charged Higgs boson from one particular representation than others. We show that such different representations can be probed an distinguished via looking at single charged Higgs boson phenomenology at the LHC with 14 TeV center of mass energy within ∼ 50 fb −1 of integrated luminosity.
