Measuring trilinear Higgs couplings in the MSSM

Trilinear couplings of the neutral CP-even Higgs bosons in the Minimal Supersymmetric Standard Model (MSSM) can be measured through the multiple production of the lightest CP-even Higgs boson (h) at high-energy e + e colliders. This includes the production of the heavier CP-even Higgs boson (H) via e + e ! ZH, in association with the CP-odd Higgs boson (A) in e + e ! AH, or via e + e ! �e¯ �eH, with H subsequently decaying through H ! hh. These processes can enable one to � � �
