Charge asymmetry in $π^+π^-$ electroproduction on proton at high energies as a test of $σ,ρ$ mesons degeneration
The charge asymmetry induced by interference of amplitudes with $σ$ and $ρ$ mesons decaying to $π^+π^-$ pair created in the fragmentation region of proton, suggest to be a test of degeneration hypothesis of $ρ$ and $σ$ mesons. Some numerical estimations are given.
