Abstract
The understanding of scalar mesons is one of the key problems of strong interaction physics.
The low-mass pion-pion data provide indications on the existence of a low-mass scalar δ
meson, however the mass and the decay width of δ meson candidate is not well known. In this
work, we calculate the coupling constant of δ meson to vector meson p and to photon by
utilizing the experimental branching ratio of p0→ π+π-γ radiative decay as a function of mass
and decay width of c-meson. We then calculate the decay rate of p0→ π0π0γ radiative decay
using this coupling constant. Measurement of this branching ratio thus may be used to
determine c meson parameters more precisely....
