Production of MSSM Higgs bosons in photon–photon collisions

The heavy neutral Higgs bosons H,A in the minimal supersymmetric extension of the Standard Model can be produced as single resonances at high-energy γγ colliders. We have studied the prospects of the search for these particles in bb̄ and neutralino-pair final states. The Higgs bosons can be found with masses up to 70–80% of the initial e±e− collider energy for medium values of tg β, i.e., in areas of the supersymmetric parameter space not accessible at other colliders.
