\title{\boldmath{ $D_1^+(2420)$}\ \ \ \ \ \ \ $***$}
\maketitle
The properties of the $D_1^+(2420)$ are less well measured than its neutral partner. The mass and width are taken from \cite{Yao:2006px}. The branching ratios are obtained by assuming that the $D^*\pi$ modes are the only ones with the rate given by isospin. The $D_1^+(2420)$ is allowed to be off-shell by five times the width.
The $D_1^+(2420)$ has mass $2423.4$~MeV and is unstable. The $D_1^+(2420)$ has spin $1$, charge $1$ and is colour neutral.
 The $D_1^+(2420)$ is a meson and is from the $1^1P_1$ multiplet.The $D_1^+(2420)$ has width $25$~MeV. The lower limit on the mass of the particle is $125$~MeV and the upper limit is $125$~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 10413.
