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 $\gamma\gamma$ colliders. Prospects of the search for these particles in $b\bar b$ 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 $\tan\beta$, i.e. in areas of the parameter space not accessible at other colliders.
