摘要：

Photon-photon linear colliders can be realized by the laser back-scattering technique in the next-generation linear e+e- colliders. Here the associated productions of an intermediate-mass Higgs (IMH) or Z boson with a ttBAR pair in gammagamma collisions are studied. Since IMH is very unlikely to decay into a ttBAR pair, ttHBAR production is the only direct channel to probe the Higgs-top Yukawa coupling in the case of an IMH. ttZBAR production can be a potential background to ttHBAR if the Higgs mass is close to m(Z). As an alternative to its parent e+e- collider, gammagamma --> ttH(Z)BAR productions are compared with the corresponding productions in the e+e- collisions.
