Understand
Cherenkov gluons may be responsible for the asymmetry of dilepton mass spectra near rho-meson observed in experiment.
- 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.
