Abstract

The reaction γγ→3 π⁺3 π^- has been studied usig the JADE detector at PETRA. The topological cross section σ(γγ→3 π⁺3 π^-) was measured in the CM energy range 1.5-5.5 GeV. The production of ρ^0,s was observed and the average number of ρ^0,s per event measured. The contributions of the subprocesses γγ→ρ⁰2 π⁺2 π^-, γγ→ρ⁰ρ⁰π⁺2 π^- and γγ→ 3 π⁺3 π^- (phase space) were studied and 95% C.L. upper limits for the cross section σ(γγ→ρ⁰ρ⁰π⁺π^- determined. Finally the Bose-Einstein correlation for pairs of like signed pions was observed. A fit to a standard parametrization gave results consistent with other studies of this effect in pion systems.
