Laser-assisted charged Higgs pair production in Inert Higgs Doublet Model (IHDM)

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 laserassisted 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.

Advances in QED with intense background fields

“…to raise their energies, giving better access to Higgs physics [970]. Some recent work has begun a program of studying treelevel processes, again in circularly polarised, monochromatic plane waves and again investigating Higgs production [971,972,973], as well as kaon decay, CPT symmetry violation [974], Z-boson production [975] and electron-neutrino scattering [976]. There is clearly scope for updating such investigations to include progress made in recent years.…”
