Anomalous gauge couplings of the Higgs boson at high energy photon colliders

Abstract

We study the sensitivity of testing the anomalous gauge couplings $g_{HVV}$'s of the Higgs boson in the formulation of linearly realized gauge symmetry via the processes $\gamma \gamma \to ZZ$ and $\gamma \gamma \to WWWW$ at polarized and unpolarized photon colliders based on $e^{+}{e}^{-}$ linear colliders of c.m.~energies 500 GeV, 1 TeV, and 3 TeV. Signals beyond the standard model (SM) and SM backgrounds are carefully studied. We propose certain kinematic cuts to suppress the standard model backgrounds. For an integrated luminosity of 1 ab${}^{-1}$, we show that (a) $\gamma \gamma \to ZZ$ can provide a test of $g_{H\gamma \gamma }$ to the $3\sigma$ sensitivity of $O(10^{-3}-10^{-2})$ TeV${}^{-1}$ at a 500 GeV ILC, and $O(10^{-3})$ TeV${}^{-1}$ at a 1 TeV ILC and a 3 TeV CLIC, and (b) $\gamma \gamma \to WWWW$ at a 3 TeV CLIC can test all the anomalous couplings $g_{HVV}$'s to the $3\sigma$ sensitivity of $O(10^{-3}-10^{-2})$ TeV${}^{-1}$.
