A unified approach for the hadronic weak decays of $\Lambda$ and ${\Sigma }^{\pm }\to N\pi$

Ye Cao, Ming-Xiao Duan, Zhong Tao +1

We provide a unified approach for the two-body hadronic weak decays of hyperons with $S=-1$, i.e. $\Lambda$ and ${\Sigma }^{\pm }$, in the framework of the non-relativistic constitute quark model (…
