One-loop QED and weak corrections to γγ → H±H∓ in the Inert Doublet Model
A bstract: We present a complete one-loop analysis of charged scalar boson pair production in photon-photon collisions, γγ → H ± H ∓ , within the framework of the Inert Doublet Model (IDM). The calculation is carried out in the on-shell renormalization scheme and incorporates both weak corrections and QED effects, including soft and hard photon radiation. Virtual loop contributions and real emission processes are computed using the Feynman diagrammatic method, ensuring the cancellation of ultraviolet and infrared divergences. To properly account for the Coulomb singularity that arises in the QED sector near threshold, we introduce the resummed cross section based on the Sommerfeld factor. The IDM parameter space is explored under theoretical consistency conditions, collider limits, and dark matter constraints, and three representative scenarios are studied in detail. We find that the magnitude of the quantum corrections is strongly controlled by the absolute value of the trilinear scalar coupling $$ {\lambda}_{h^0{H}^{+}{H}^{-}} $$ , which correlates with the charged scalar mass. When all constraints are applied, the weak corrections are typically in the range of −12% to −7% at $$ \sqrt{s}=250 $$ GeV, and between −15% and 6% at $$ \sqrt{s}=500 $$ GeV. At higher energies, such as $$ \sqrt{s}=1 $$ TeV, the corrections can become very large, ranging from about −20% up to +60%. Our findings highlight the significant role of higher-order effects in photon-photon collisions and establish γγ → H ± H ∓ as a promising process to investigate the charged scalar sector of the IDM at future high-energy photon colliders. Several benchmark points are proposed to facilitate future experimental searches.- 26 March 2026

Revisiting inert doublet model parameters
In this study, we aim to see how much the actual measurement of the Z+photon and di-photon signal strength, $$\mu _{\gamma \gamma }$$ and $$\mu _{\gamma Z}$$ , could influence the allowed parameter space of the Inert Doublet Model (IDM), and to what extent such measurement can be aligned with the latest bound from XenonNT experiment on the spin-independent dark-matter-nucleon scattering cross-section. Also, by considering the new embedded scalars in the IDM (i.e., S, A and $$H^\pm $$ ), a wide investigation of the one-loop radiative corrections to the trilinear Higgs coupling hhh has been made in the light of the previous measurements.- 25 June 2024

The oblique parameters in the 2HDM with vector-like quarks: confronting M W CDF-II anomaly
The CDF collaboration has released a new measurement of the W boson mass using their complete data set with 8.8 fb−1 in p p ¯ collisions. This result deviates from the Standard Model prediction by around 7σ. We explain how the two Higgs doublet model (2HDM) with vector-like quarks (VLQs) is affected by the recently discovered W boson mass. In our study, we include both theoretical constraints such as perturbative unitarity and vacuum stability as well as a number of experimental constraints. We also look into how the effective mixing angle, measured by the SLD collaboration in addition to the CDF W-boson mass, is used to determine the S and T parameters. In the alignment limit, we investigate the case where the lighter CP-even neutral Higgs boson of the 2HDM is the one found at the LHC and demonstrate how the parameter space of the 2HDM type II in the presence of VLQs is constrained. It is found that in most cases, there is a cancellation between the 2HDM and VLQs contributions, which enlarges the parameter space of both models.

In the scenario where all the constraints are taken into account, we find that for $\sqrt{s}=250$ GeV and $\sqrt{s}=500$ GeV, the weak corrections are around $-6\% \sim-5\%$ and $-10\% \sim -3\%$, respectively. While for $\sqrt{s}=1000$ GeV, the weak corrections can reach $-15\% \sim +25\%$.

Pair charged Higgs productions at NLO in e+ e- collider within the Inert Doublet model .
In this contribution, we investigate the complete electroweak one-loop radiative correction to the $e^+e^-\to H^+H^-$ 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 $e^+e^-\to H^+H^-$ process, the detection of the new physics of IHDM can be directly done due to the large production rate and the corrections are significant.- 27 March 2023

In the present paper, we study the Two-Higgs Doublet Model (2HDM) contributions to $M_W$ and its phenomenological implications in the case where the heavy CP-even $H$ is identified as the observed Higgs boson with a mass of $125$ GeV. Taking into account theoretical and all the available experimental constraints as well as the new CDF measurement, we demonstrate that the 2HDM parameter space can provide a large correction which predicts the W mass close to the new CDF $M_W$ measurement. It is found that $M_{H\pm}=M_A$ is excluded and the splitting of the charged Higgs boson with all other states is positive.

One-loop radiative corrections to e+e− → Zh0/H0A0 in the Inert Higgs Doublet Model
We compute the full one-loop radiative corrections (including both weak and QED corrections) for two processes e+e− → Zh0, H0A0 in the Inert Higgs Doublet model (IHDM). Up to O(αw) and O(αem) order, we use FeynArts/FormCalc to compute the one-loop virtual corrections and Feynman Diagram Calculation (FDC) to evaluate the real emission, respectively. Being equipped with these computing tools, we investigate radiative corrections of new physics for five scenarios with three typical collision energies of future electron-positron colliders: 250 GeV, 500 GeV, and 1000 GeV. By scanning the parameter space of IHDM, we identify the allowed regions which are consistent with constraints and bounds, from both theoretical and experimental sides. We find that the radiative corrections of the IHDM to e+e− → Zh0 can be sizeable and are within the detection potentials of future Higgs factories. We also find that the new physics of IHDM could also be directly detected by observing the process e+e− → H0A0 which could have large enough production rate. We propose six benchmark points and examine their salient features which can serve as physics targets for future electron-positron colliders, such as CEPC/CLIC/FCC-ee/ILC as well as for LHC.
