Asymmetry of in-medium rho-mesons as a signature of Cherenkov effects

Dremin, I. M., Nechitailo, V. A.

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.
