$\Lambda _c \to p\bar K^0 \pi \pi$ and$\Lambda _c \to p\bar K^0$ decay rates

Abstract

Available phase space suppresses the decay$\Lambda _c^ + \to p\overline {K^0 } \pi ^ + \pi ^ -$ in comparison with the decay$\Lambda _c^ + \to p\overline {K^0 }$. However, their comparable decay rates, as found experimentally, can be explained by the strong interaction induced tree diagrams in which pions are emitted along the final baryon leg.
