ρ{variant} → 4π decay

Eidelman S. I., Silagadze Z. K., Kuraev E. A.

The decay modes ρ{variant}0→2π+2π- and ρ{variant}0→2π0π+π- are considered in the framework of the low energy effective chiral Lagrangian. The obtained values of the decay withs Γ(ρ{variant}0→2π+2π-) = (16±1) keV and Γ(ρ{variant}0→2π0π-) = (6.0±0.2) keV do not contradict the existing upper limits and seem to be large enough for the corresponding processes to be observed in future high luminosity experiments. © 1995.
