Photoproduction of the Scalar Meson $f_0(500)$

In the present talk, we report a recent investigation on photoproduction of the $gamma N to f_0(500)N$ within a framework of the effective Lagrangian. We include the nucleon resonances with pin $1/2$ in the $s$ channel. The coupling constants have been etermined by assuming that the decay process $N^* to (pipi)_{I=0,J=0}N$ can be regarded as $N^* to f_0(500) N$. We discuss the numerical results for the total cross sections and possible extension of the present work.
