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

Abstract

We present the first study of production of ψ(4040), ψ(4160), and ψ(4415) mesons in hadronic matter. Quark interchange between two colliding charmed mesons leads to the production of the three mesons. We calculate unpolarized cross sections for the reactions,
