Probing the Scalar Sector in $e^+ e^- \rightarrow f \bar{f} H$
Abstract
Description
We study possible deviations from the Standard Model in the reaction $e^+e^- \to Zϕ$, 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.
