Production of $\psi (4040)$, $\psi (4160)$, and $\psi (4415)$ mesons in hadronic matter

Li-Yuan Li, Xiao-Ming Xu, H. J. Weber

We present the first study of production of $\psi (4040)$, $\psi (4160)$, and $\psi (4415)$ mesons in hadronic matter. Quark interchange between two colliding charmed mesons leads to the produ…
