\title{\boldmath{ $f_0(1500)$}\ \ \ \ \ \ \ $***$}
\maketitle
The properties of the $f_0(1500)$ are not accurately measured, in common with other scalar mesons. The mass and width are taken from \cite{Yao:2006px} as are most of the branching ratios. We use the branching ratios from \cite{Yao:2006px} for the main modes but use the results from \cite{Abele:2001js}  to split the four pion mode up into submodes. The $f_0(1500)$ is allowed to be off-shell by three times the width. The branching ratios vary with the off-shell mass due to problems with the $\eta\eta'$ decay mode for masses below the central value.
The $f_0(1500)$ has mass $1507$~MeV and is unstable. The $f_0(1500)$ has spin $0$, charge $0$ and is colour neutral.
 The $f_0(1500)$ is a mesonThe $f_0(1500)$ has width $109$~MeV. The lower limit on the mass of the particle is $327$~MeV and the upper limit is $327$~MeV. These are the deviations from the on-shell value. The branching ratios are allowed to vary with the off-shell mass of the particle.
The properties of the particle and its antiparticle are taken to be charge-conjugate to each other.
 The PDG code is 9030221.
