英文摘要: With the diquark structure of Lambda(c), we investigate the branching ratio of Lambda(c)-->npi(+) and ppi(0). The results show that without considering the final state interaction (FSI), the branching ratio of Lambda(c)-->ppi(0) is only of order 10(-6) whereas this ratio could reach 10(-4) and is at the same order as Lambda(c)-->npi(+) if taking into account the FSP effects. Concrete values, depend on phenomenological parameters adopted in the calculations. These branching ratios can be measured in the experiments to come.
