The ρ-meson time-like form factors in sub-leading pQCD
The annihilation/production process e++e−→ρ++ρ− is studied with respect to the universal perturbative QCD (pQCD) predictions. Sub-leading contributions are considered together with the universal leading pQCD amplitudes such that the matrix elements of the ρ-meson electromagnetic current satisfy the...
