Charge asymmetries in diffractive electroproduction of two mesons are proportional to the interference of Pomeron and Odderon exchange amplitudes. We calculate in the framework of QCD and in the Born approximation a forward-backward charge asymmetry which turns out to be sizable in a kinematical domain accessible to HERA experiments. We predict a distinctive dependence of this asymmetry on the invariant mass of the two pions. Testing this prediction is a crucial step in the discovery of the QCD-Odderon.

    The paper proposes using two-photon exchange interference in e+e- to (pi pi)(pi pi) to access chiral-odd dimeson GDAs that encode spin-orbit correlations in spin-zero mesons.
