Abstract
The process gamma --> ZH first arises at the one loop level, and as such it provides us with remarkable tests of the structure of the electro-weak Higgs sector. These tests are complementary to those in the gauge sector involving gamma gamma --> gamma, gammaZ, ZZ. We show that in the standard model(SM) where H = H-SM, as well as in the supersymmetric ease where H = h(0),H-0 or A(0), observables exist (like e.g. the energy dependence, angular distribution, photon polarization dependence or final Z polarization) which present rather spectacular properties. Such properties involve strong threshold effects with steps, bumps or peaks, reflecting the type of Higgs and heavy quarks and chargino masses and couplings predicted by the SM and supersymmetric models.
