Abstract :
The decay modes ϱ0→2π+2π− and ϱ0→2π0π+π− are considered in the framework of the low energy effective chiral Lagrangian. The obtained values of the decay withs Γ(ϱ0→2π+2π−) = (16±1) keV and Γ(ϱ0→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.
