Summary: | J.Phys.G30:663-676,2004 We analyze the mass spectroscopy of low and high mass scalar mesons and get
the result that the coupling strengths of the mixing between low and high mass
scalar mesons are very strong and the strengths of mixing for $I=1, 1/2$ scalar
mesons and those of I=0 scalar mesons are almost same. Next, we analyze the
decay widths and decay ratios of these mesons and get the results that the
coupling constants $A'$ for $I=1, 1/2$ which represents the coupling of high
mass scalar meson $N'$ -> two pseudoscalar mesons $PP$ are almost same as the
coupling $A'$ for the I=0. On the other hand, the coupling constant $A$ for
$I=1, I=1/2$ which represents the low mass scalar meson $N$ -> $PP$ are far
from the coupling constant $A$ for I=0. We consider a resolution for this
discrepancy. Coupling constant $A''$ for glueball $G$ -> $PP$ is smaller than
the coupling $A'$. $\theta_P$ is $40^\circ \sim 50^\circ$. |
