Production of MSSM Higgs bosons at future γγ colliders.

Future γγ colliders allow the production of the heavy neutral MSSM Higgs bosons H and A as single resonances. The prospects of finding these particles in the b&bmacr; and the neutralino-pair final states have been analysed. The H, A bosons can be discovered for medium values of tan β with masses up to 70–80% of the initial e[sup ±]e[sup -] c.m. energy. This production mode thus covers parts of the supersymmetric parameter space that are not accessible at other colliders. [ABSTRACT FROM AUTHOR]
