摘要

我们研究了所有轻扇区和重扇区中运动学允许的重子到重子-介子的强跃迁。我们只考虑重子和中子通道中的基态壳层粒子。在介子的情况下，只涉及已建立的伪恒星和矢量粒子。对于重子，我们考虑基态自旋为1/2和3/2的重子。使用所有的限制和守恒定律，mathematica/ python代码在许多可能的转换中选择允许的强通道。利用定义这些跃迁的强耦合常数，我们估计了每个通道的强宽度和搁浅率，这可能有助于正在进行的实验和理论研究。

The allowed baryon to baryon–meson strong transitions

We investigate the kinematically allowed baryon to baryon–meson strong transitions in all the light and heavy sectors. We consider only the ground state on-shell particles in the baryonic and mesonic channels. In the case of mesons, only the well-established pseudoscslar and vector nonets are involved. For the baryons, we consider the ground state spin 1/2 and 3/2 baryons. Using all the restrictions and conservation laws, a mathematica/ python code selects the allowed strong channels among many possible transitions. Using the strong coupling constants defining these transitions, we estimate the strong width and beaching fraction at each channel, that may help ongoing experimental and theoretical investigations.
