Production of MSSM Higgs Bosons in $\gamma \gamma$ Collisions

Abstract

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.
