\title{\boldmath{ $\bar{n}^0(1440)$}\ \ \ \ \ \ \ $****$}
\maketitle
The neutral mebmer of first excited multiplet of nucleon-like baryons. The mass and width are taken from \cite{Yao:2006px}. The branching ratios use the central values from \cite{Yao:2006px} with minor adjustments to ensure the branching ratios sum to one.
The lower limit on the mass is set so that the $N\pi$ mode is allowed and the upper limit to twice the width. Given the small mass differences for the $N\pi\pi$ and $\Delta\pi$ modes the option of varying the branching ratios with the off-shell mass is used to pervent the unaccessible decay modes being selected.
The $\bar{n}^0(1440)$ has mass $1440$~MeV and is unstable. The $\bar{n}^0(1440)$ has spin $1/2$, charge $0$ and is colour neutral.
 The $\bar{n}^0(1440)$ is a baryon$40$plet.The $\bar{n}^0(1440)$ has width $300$~MeV. The lower limit on the mass of the particle is $300$~MeV and the upper limit is $600$~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 -12112.
