Probing the Scalar Sector in e + e − → f ¯ fH .

We study possible deviations from the Standard Model in the reaction e + e − → Zφ , where φ denotes a spinless neutral boson. We show how the Z decay angular correlation can be used to extract detailed information on the φ couplings, such as the parity of φ , 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.
