Higgs-strahlung boson production in the presence of a circularly polarized laser field

TL;DR

This paper studies how a circularly polarized laser field influences Higgs boson production in electron-positron annihilation, revealing significant reductions in cross section compared to laser-free scenarios.

Contribution

It provides the first detailed analysis of laser field effects on Higgs production in the electroweak model, highlighting substantial cross section suppression.

Findings

Total cross section decreases by several orders of magnitude with laser field presence.

Laser parameters significantly impact Higgs production rates.

Results are consistent with previous findings on muon pair production in laser fields.

Abstract

In the framework of the electroweak standard model, we investigated, in the center of mass frame, the Higgs boson production in the presence of an intense laser field via ${e}^{+} {e}^{-}$ annihilation $({e}^{+} {e}^{-}\rightarrow ZH)$. By comparing our results with those obtained by Djouadi \cite{1} for laser-free process, we show that the circularly polarized laser field affects significantly the $s$-channel Higgs boson production. We find that for a given number of exchanged photons, laser field strength and frequency, the total cross section decreases by several orders of magnitude. These effects of laser field on cross section are found to be consistent with what was found for muon pair production via QED process in the presence of a circularly polarized laser field \cite{2}.
