研究了反核子湮灭过程中相干介子产生的全量子力学描述。两种不同的反应机制,包括初始和最终状态的相互作用,这都是来自折叠的方法。基本的反核子-核子bar N N和π-核子πN相互作用进入光学势,光学势与Hartree-Fock-Bogoliubov核密度折叠.现有的方法已经扩展到更高的能量超过Δ-共振π核相互作用。显示了横截面。
The study of a fully quantum mechanical description of coherent meson production in antinucleon annihilation on nuclei is presented. Two different reaction mechanisms are presented including initial and final state interactions, which are both derived from a folding approach. The underlying fundamental antinucleon-nucleon bar N N and pion-nucleon πN interactions enter into the optical potentials, which are folded with Hartree-Fock-Bogoliubov nuclear densities. Existing approaches to pion nucleus interactions have been extended to higher energies beyond the Δ-resonance. Cross sections are shown.
