Abstract

The production of a pair of charged Higgs bosons from e+e− annihilation in the presence of a circularly polarized laser field is investigated in Inert Higgs doublet Model (IHDM) at e+e− colliders. We have derived the analytical expression for the laser-assisted differential cross section by using the Dirac-Volkov formalism at leading order including the Z and γ diagrams. Since the laser-free cross section of this process depends, in the lowest order, only on the mass of the charged Higgs boson and the energy of the center of mass, we have analyzed the dependence of the total laser-assisted cross section on these parameters and also on the laser parameters such as the number of photons exchanged, the laser field intensity and its frequency. The results found indicate that the electromagnetic field decreases the order of magnitude of the total cross section as much as the laser field intensity increases or by decreasing its frequency. Moreover, it becomes high for low charged Higgs masses and low center of mass energies.

Highlights

Since its inception in 1960, laser technology has made significant advances, in terms of increasing its intensity and decreasing its pulse duration [1, 2]
The production of double charged Higgs boson in the presence of a circularly polarized laser field is considered for study at different center of mass energies within the Inert Higgs doublet Model (IHDM) model at future electron-positron colliders such as Compact Linear Collider (CLIC) [30], International Linear Collider (ILC), [31,32] FCC-ee and Circular Electron Positron Collider (CEPC) [33,34]
The first step in this discussion concerns the behavior of the partial total cross section, which corresponds to each four-momentum conservation δ(p3 + p4 − q1 − q2 − nk) = 0, as a function of the number of exchanged photons

Summary

Introduction

Since its inception in 1960, laser technology has made significant advances, in terms of increasing its intensity and decreasing its pulse duration [1, 2]. Models accounting for dark matter can be embedded within beyond SM In this respect, the production of double charged Higgs boson in the presence of a circularly polarized laser field is considered for study at different center of mass energies within the IHDM model at future electron-positron colliders such as Compact Linear Collider (CLIC) [30], International Linear Collider (ILC), [31,32] FCC-ee and Circular Electron Positron Collider (CEPC) [33,34]. The production of double charged Higgs boson in the presence of a circularly polarized laser field is considered for study at different center of mass energies within the IHDM model at future electron-positron colliders such as Compact Linear Collider (CLIC) [30], International Linear Collider (ILC), [31,32] FCC-ee and Circular Electron Positron Collider (CEPC) [33,34] These types of colliders, which possess a very clean environment, will generate precise results and will operate with various collision energies. The expression of the squared total scattering amplitude is given in the appendix
