“…With the highluminosity designed at future LCs [3], the signal of Higgs boson production associated with a photon can be probed. Many computations for one-loop corrections to at future LCs in the SM are available [58][59][60], such as those in many frameworks of the HESM [61][62][63] and in the minimal supersymmetric standard model [64]. In this work, we show that cross-sections of can be derived by using one-loop form factors in .…”

We present one-loop contributingfor $h\rightarrow \ell \bar{\ell}\gamma$with $\ell =\nu_{e,\mu, \tau}, e, \mu$ and $e^-e^+\rightarrow h\gamma$ in $U(1)_{B-L}$ extension of the standard models. In phenomenological results, the signal strengths for $h\rightarrow \ell \bar{\ell}\gamma$ at Large Hadron Collider and for $e^-e^+\rightarrow h\gamma$at future Lepton Collidersare analyzed in physical parameter space for both vector and chiral $B-L$ models. We find that the contributions from neutral gauge boson $Z'$ to the signal strengths are rather small. Consequence, the effects are hard to probe at future colliders.While the impacts of charged Higgs in the chiral $B-L$ model on the signal strengthsare significant and can be measured with the help of the initial polarization beams at future lepton colliders.Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

“…The low-scale Type II Seesaw can be experimentally accessible at high-energy colliders when the triplet Higgs mass M ∆ is at TeV level. The searches of the triplet Higgs have been studied extensively at the Large Hadron Collider (LHC) [15,, its upgrades [53,55,[60][61][62][63][64], leptonic colliders [65][66][67][68][69][70][71][72][73][74][75][76][77][78][79][80][81] and ep collider [82,83], in terms of lepton number violation (LNV) signatures for H ±± and H ± . The decay modes of charged Higgs bosons can be categorized into leptonic decays and the decays to vector bosons.…”

The future muon collider can play as an ideal machine to search for new physics at high energies. In this work, we study the search potential of the heavy Higgs triplet in the Type II Seesaw mechanism at muon colliders with high collision energy and high luminosity. The latest neutrino oscillation data are taken into account for realizing the leptonic decay modes of the charged Higgs bosons (H±±, H±) in the Type II Seesaw. We show the impact of neutrino mass and mixing parameters on the purely leptonic decays. The pair production of doubly charged Higgs H++H−− is through direct μ+μ− annihilation and vector boson fusion (VBF) processes at muon collider. The associated production H±±H∓ can only be induced by VBF processes. We simulate both the purely leptonic and bosonic signal channels of charged Higgs bosons in Type II Seesaw, together with the Standard Model backgrounds. We show the required luminosity for the discovery of the charged Higgses and the reachable limits on the leptonic decay branching fractions.

“…The pair production of charged Higgs boson as well as neutral higgs boson from e − e + annihilation are analyzed within many extensions BSM, whether in Inert Higgs Doublet Model (IHDM) [18], Two Higgs Doublet Model (2HDM) [19], or in the SM which is extended with Triplet (HTM) [20]. Moreover, the process which acts as a source of charged Higgs boson H ± associated with a W ∓ boson at e + e − collider is studied [21], and the signal process proceeds through s-channel via virtual γ and Z-boson exchange.…”

In this study, we have investigated the production of a charged Higgs boson in assiciation with a charged weak W -boson (H ± W ∓ ) at tree level via e + e − annihilation in the presence of a laser field with circular polarization. At first step and by using analytical techniques, we have derived the expression of the differential cross section involving both Z and γ diagrams. Next, we have shown that the cross section of this process inside the laser field is proportional to the form factor F HW V , and it depends on the mass of the charged Higgs boson and the energy of the center of mass. Then, we have analyzed the dependence of the total laser-assisted cross section on the number of photons exchanged for two different cases of form factor. Finally, we have found that the maximum number of photons that can be transferred depends only on the laser parameters.
