We study the full contributions at the leading order(LO) and QCD next-to-leading order(NLO) to the cross section of the e + e − → W + W − b b process in the standard model(SM) at the ILC. In dealing the resonance problem we adopted the complex mass scheme in both treelevel and one-loop level perturbative calculations. Our numerical results show that the K-factor varies from 1.501 to 0.847 when √ s goes up from 360 GeV to 1.5 T eV . We investigate the dependence of the LO and QCD NLO corrected cross sections of process e + e − → W + W − b b on colliding energy √ s and Higgs-boson mass. We also present the results of the LO and QCD NLO corrected distributions of the transverse momenta of final particles, and the invariant masses of W b-, b band W W -pair.

Exploring the prominent channel: Charged Higgs pair production in supersymmetric two-parameter non-universal Higgs model

In this study, the charged Higgs pair production is calculated in the context of the supersymmetry at a γγ-collider. The channel is explored in Two-parameter Non-Universal Higgs Model where the model provides relatively light neutral and charged Higgs bosons. The computation is extended to one loop-level, and the divergence arising in the loop-diagrams are cured with the radiative photon correction. The production rate of the charged Higgs pair reaches up toσ LO+NLO UU = 121 fb at √ŝ = 635 GeV. The analysis of the cross-section is also given varying the parameters mA and tan β. The total convoluted cross-section with the photon luminosity in an e + e − machine is calculated as a function of the center-of-mass energy up to 1 TeV, and it gets up to 42 fb at √ s = 900 GeV depending on the polarization of the initial electron and laser photon.

“…The charged Higgs boson pair production in the γγ → H + H − mode was considered in [23][24][25]. In general, the higher-order corrections to the γγ → H + H − subprocess decrease the tree-level total cross section by about a few percent; see [26,27]. Also the associated production γγ → H ± W ∓ was discussed in the literature [28].…”

We calculate differential cross sections for exclusive production of heavy charged scalar, weakly interacting particles (charged Higgs bosons, charged technipions, etc.) via photon-photon exchanges in the pp → ppH + H − reaction with exact 2 → 4 kinematics. We present distributions in rapidities, transverse momenta, and correlations in azimuthal angles between the protons and between the charged Higgs bosons. As an example, the integrated cross section for √ s = 14 TeV (LHC) is about 0.1 fb and about 0.9 fb at the Future Circular Collider (FCC) for √ s = 100 TeV when assuming m H ± = 150 GeV. The results are compared with results obtained within standard equivalent-photon approximation known from the literature. We discuss the role of the Dirac and Pauli electromagnetic form factors of the proton. We have also performed first calculations of cross sections for the exclusive diffractive Khoze-Martin-Ryskin mechanism. We have estimated limits on the g hH + H − coupling constant within two-Higgs dublet model based on recent experimental data from the LHC. The diffractive contribution is, however, much smaller than the γγ one. The Zγ, γZ, and ZZ exchanges give even smaller contributions. Absorption corrections are calculated for the first time differentially for various distributions. In general, they lead to a damping of the cross section. The damping depends on the M H + H − invariant mass and on t fourmomentum transfers squared. In contrast to diffractive processes, the larger the collision energy, the smaller the effect of absorption. We discuss a possibility to measure the exclusive production of two charged Higgs bosons with the help of so-called "forward proton detectors" at the LHC experiments.
