AbstractWe 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 -> ZZ and gamma gamma -> 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 -> 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 -> 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).
