| Abstract: | With the diquark structure of Λc, we investigate the branching ratio of Λc→nπ+ and pπ0. The results show that without considering the final state interaction (FSI), the branching ratio of Λc→pπ0 is only of order 10-6 whereas this ratio could reach 10-4 and is at the same order as Λc→nπ+ if taking into account the FSI effects. Concrete values depend on phenomenological parameters adopted in the calculations. These branching ratios can be measured in the experiments to come. |
