Induced Fission-Like Process of Hadronic Molecular States
文献摘要：
We predict a new physical phenomenon,induced fission-like process and chain reaction of hadronic molecular states.As a molecular state,if induced by a D meson,the X(3872)can split into DD final state which is forbidden due to the spin-parity conservation.The breeding of the D meson of the reaction,such as D0X(3872)→D0(D)0D0,makes the chain reaction of X(3872)matter possible.We estimate the cross section of the D meson induced fission-like process of X(3872)into two D mesons.With very small D0 beam momentum of 1eV,the total cross section reaches an order of 1000 b,and decreases rapidly with the increasing beam momentum.With the transition of D* meson in molecular states to a D meson,the X(3872)can release large energy,which is acquired by the final mesons.The momentum distributions of the final D mesons are analyzed.In the laboratory frame,the spectator D meson in molecular state concentrates in the low momentum area.The energy from the transition from D* to D meson is mainly acquired by two scattered D mesons.The results suggest that the D meson environment will lead to the induced fission-like process and chain reaction of the X(3827).Such a phenomenon can be extended to other hadronic molecular states.
