Probing the Scalar Sector in $e^{+}{e}^{-}\to f\bar{f}H$

We study possible deviations from the Standard Model in the reaction $e^+e^- \to Z\phi$,where$\phi$denotesaspinlessneutralboson\mathrm{.}Weshowhowthe$Z$decayangularcorrelationcanbeusedtoextractdetailedinformationonthe$\phi$couplings,suchastheparityof$\phi$, radiatively induced form factor effects and possible CP violation in the scalar sector. Consequences of gauge invariant dimension six operators are discussed as an example.
