Single Charged Higgs Boson Production in Polarized Photon Collision and the Probe of New Physics

Abstract

We study single charged Higgs boson production in photon-photon collision as a probe of the new dynamics of Higgs interactions. This is particularly important when the mass ($M_{H^{\pm }}$) of charged Higgs bosons ($H^{\pm }$) is relatively heavy and above the kinematic limit of the pair production ($M_{H^{\pm }}>\sqrt{s}/2$). We analyze the cross sections of single charged Higgs boson production from the photon-photon fusion processes, $\gamma \gamma \to \tau \bar{\nu }{H}^{+}$ and $\gamma \gamma \to b\bar{c}{H}^{+}$, as motivated by the minimal supersymmetric standard model and the dynamical Topcolor model. We find that the cross sections at such a $\gamma \gamma$ collider can be sufficiently large even for $M_{H^{\pm }}>\sqrt{s}/2$, and is typically one to two orders of magnitude higher than that at its parent $e^{-}{e}^{+}$ collider. We further demonstrate that the polarized photon beams can provide an important means to determine the chirality structure of Higgs Yukawa interactions with the fermions.
