Abstract

We study Pomeron-Odderon interference effects giving rise to charge and single-spin asymmetries in diffractive electroproduction of a π⁺ π^- pair. The final state interactions and the role of f₀ meson are discussed. The absence of f₀ signal in the charge asymmetry observed by HERMES may be due to the smalness of its quark component.
