Production of MSSM Higgs bosons in γγ collisions

The heavy Higgs bosons H,A of the minimal supersymmetric extension of the Standard Model can be produced as resonances in high-energy γγ colliders. Prospects of the search for these particles in bb̄ and neutralino-pair final states are studied in this report. Heavy Higgs bosons can be found with masses up to about 70–80% of the initial e+e− collider energy for moderate values of tan β, i.e. in areas of the parameter space not accessible at other colliders.
