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.
Lattice QCD now delivers high-precision results on hadron internal structure that directly support the scientific program of the Electron-Ion Collider.
