\begin{itemize}
\item Is the description present and correct?

The $\eta$ is the lightest of the isospin singlet mesons from the $1^1S_0$ multiplet. The decay modes and properties are taken from \cite{Yao:2006px}, together with some minor modifications to the branching ratios of the dominant modes to ensure the branching ratios sum to one. The $\eta$ is allowed to be off-shell by ten times the width.
\item References?
