Higgs bosons: Intermediate mass range ate+e−colliders

We elaborate on the production of the standard model Higgs particle at high-energy $e^{+}{e}^{-}$ colliders through the reaction $e^{+}{e}^{-}\to \mathrm{ZH}$. Particular emphasis is put on the intermediate mass range. In addition to the signal we discuss in detail the background processes. Angular distributions which are sensitive to the spin and parity of the Higgs particle are analyzed.
