Scientific paper

We examine the mixing between the sigma meson $\sigma$ and the "pure"
glueball field $H$ and study the decays of the scalar glueball candidate
$f_0(1500)$ (a linear combination of $\sigma$ and $H$) into two and four pions
in effective linear sigma model. From recent experimental data on $f_0(1500)$
decay to pions we point out that the mixing angle is of order of 0.1.
