We update theoretical studies of the physics opportunities presented by · Higgs factories. Interesting measurements of the Standard Model Higgs decays into , · and Ï Ï £ may be possible if the Higgs mass is less than about ½ ¼ Î, as preferred by the precision electroweak data, the mass range being extended by varying appropriately the beam energy resolution. A suitable value of the beam energy resolution would also enable the uncertainty in the -quark mass to be minimized, facilitating

These measurements would be sensitive to radiative corrections to the Higgs-fermion-antifermion decay vertices, which may violate CP. Radiative corrections in the MSSM may also induce CP violation in Higgs-mass mixing, which can be probed via various asymmetries measurable using polarized · beams. In addition, Higgs-chargino couplings may be probed at a second · Higgs factory.
