Description
A meson-theoretical model for the reaction π-p → π0π0n for large π- momenta is developed which treats the final-state interaction between the two produced pions microscopically. For small momentum transfers, the squares of the S-wave amplitudes of the produced two-pion system show a dip for invariant two-pion masses in the vicinity of the f0(980) meson, while for momentum transfers -t > 0.2 (GeV/c)2, the f0 (980) meson appears as a bump. The model provides a microscopic explanation of the long-standing puzzle seen by both the GAMS and the BNL experimental collaborations
