Induced Fission-Like Process of Hadronic Molecular States

In this work, we predict a new physical phenomenon, induced fission-like process and chain reaction of hadronic molecular states. As state, if by $D$ meson, the $X(3872)$ can split into $D\bar{D}$ final state which is forbidden due to spin-parity conservation. The breeding meson reaction, such as $D^0X(3872)\to D^0\bar{D}^0D^0$, makes matter possible. We estimate cross section two mesons. With very small $D^0$ beam momentum 1 eV, total reaches an order 1000 b, decreases rapidly with increasing momentum. transition $D^*$ in states release large energy, acquired distributions mesons are analyzed. laboratory frame, spectator concentrates low area. energy from frim mainly scattered results suggest that environment will lead $X(3827)$. Such phenomenon be extended other
