\title{\boldmath{ $\Lambda^0(1690)$}\ \ \ \ \ \ \ $****$}
\maketitle
The $\Lambda^0(1690)$ is the light singlet from the first spin-$3/2$ nucleon like multiplet. The mass, width and branching ratios are taken from \cite{Yao:2006px}. The particle is allowed to be off-shell by four times the width to ensure the decays are kinematically allowed.
The $\Lambda^0(1690)$ has mass $1690$~MeV and is unstable. The $\Lambda^0(1690)$ has spin $3/2$, charge $0$ and is colour neutral.
 The $\Lambda^0(1690)$ is a baryon$40$plet.The $\Lambda^0(1690)$ has width $60$~MeV. The lower limit on the mass of the particle is $240$~MeV and the upper limit is $240$~MeV. These are the deviations from the on-shell value. The branching ratios are fixed.
The properties of the particle and its antiparticle are taken to be charge-conjugate to each other.
 The PDG code is 13124.
