“…The sign of the correction becomes negative at higher energies [41]. The full one-loop radiative corrections to e + e − → Zh/H 0 A 0 processes in the inert doublet model has been recently calculated [43]. The Higgs diphoton decay rate including the BSM contribution can be readily obtained by means of the well known loop functions.…”

We compute the one-loop corrections to σ(e+e−→ Zh) arising from representative extended Standard Model scalar sector scenarios. According to the new scalar SU(2)L representations, we consider the inert doublet, real and complex triplet, quintuplet, and septuplet models. With the sub-percent level precision expected for prospective future e+e− collider measurements of σ(e+e−→ Zh), studies of the Higgsstrahlung process will probe extended scalar sector particle spectrum and interactions in a manner complementary to direct searches at the Large Hadron Collider and possible future pp colliders. We also compare with the sensitivity of future Higgs diphoton decay rate measurements. We find that the σ(e+e−→ Zh) and Γ(h → γγ) complementarity is particularly pronounced for the complex triplet model.

“…After the discovery of the Higgs-boson, there have been several theoretical and phenomenological studies which are devoted to non-minimal Higgs sector models that can explain such discovery and address some of the standard model's weakness. One of the simplest non-minimal Higgs model is the popular IHDM which is a version of 2HDM with an exact discrete Z 2 symmetry [20]. It provides a viable dark matter candidate as the standard model scalar sector parametrized by H 1 and extended by an inert scalar doublet H 2 .…”

In the framework of the Inert Higgs Doublet model (IHDM), we have investigated, in the center of mass frame, the neutral Higgs-boson pair production in the presence of an intense and circularly polarized laser field via e + e − annihilation (e + e − → H 0 A 0 ) at the lowest order. By using the scattering matrix method, we have derived the analytical expression of the differential cross section. The latter is numerically integrated over the solid angle to obtain the total cross section. Then, we have shown how this total cross section depends on the outgoing particles mass for different number of exchanged photons. Next, we have illustrated its variation as a function of the centre of mass energy for different neutral Higgs-boson masses. Finally, we have indicated how it changes as a function of the laser field amplitudes for both different number of exchanged photons and different neutral Higgs-bosons masses.

In this contribution, we investigate the complete electroweak one-loop radiative correction to the + − → + − within the Inert Higgs Doublet Model (IHDM), at the future Higgs factory such as the ILC, CLIC and CEPC. After taking account of the theoretical and experimental constraints such as LEP, LHC and Dark matter constraints, the calculations are performed using FeynArts/FormCalc (FA/FC) to evaluate the one-loop weak corrections and using Feynman Diagram Calculation (FDC) to compute the QED contribution to the Next-Leading-Order (NLO) cross section, in three energies of collisions 250, 500 and 1000 GeV. By observing the + − → + − process, the detection of the new physics of IHDM can be directly done due to the large production rate and the corrections are significant.
