They can be produced only in the low-mass wing of the resonance. Therefore the dilepton mass spectra are flattened there and their peak is slightly shifted to lower masses compared with the in-vacuum rho-meson mass. This feature must be common for all resonances.8 pages, 1 FigHigh Energy Physics - PhenomenologyNuclear Theorytext
