Abstract

In this talk we review the current experimental status of electron-positron annihilation into π⁺π^-η as well as the theoretical models to describe the data. Application of the CVC hypothesis to get the τ^- decay to π^-π⁰η branching fraction is discussed and its values from the different experiments is listed.
