Probing the Scalar Sector in $e^{+}{e}^{-}\to Z\varphi$

Abstract

We study possible deviations from the Standard Model in the reaction $e^{+}{e}^{-}\to Z\varphi$, where $\varphi$ denotes a spinless neutral boson. We show how the $Z$ decay angular correlation can be used to extract detailed information on the $\varphi$ couplings, such as the parity of $\varphi$, radiatively induced form factor effects and possible CP violation in the scalar sector.
