Abstract
Experimental data of\(\bar pp\) annihilation into 3π0 and π+π0π− are analyzed in the quark pair creation model (3P0 Model) with planar quark diagram topology. There are two form factors depending on whether 1) the two π′s contain a quark or an antiquark that originates from ap or a\(\bar p\) respectively, or 2) one π contain a quark and an anti-quark both created from the vacuum. We call the amplitude of the first as a G-type and the latter as the an F-type. The intermediate states in G-type processes which contain correlations of the3P0 vertices in the initial state and those in the final state can be regarded as gluons of 0++ and a\(\bar qq\). The two π resonance like structure of 0++ (1520) observed in 3π0 and 2++ observed in π+π0π− can be interpreted as the interference of the G-type amplitudes with the F-type amplitudes.
