Cabibbo-suppressed non-leptonic decays of Lambdac and final state interaction
Abstract
With the diquark structure of Lambdac, we investigate the branching ratios of Lambdac -> n pi+ and p pi0. The results show that without considering the final state interaction (FSI), the branching ration of Lambdac -> p pi+ is only of order 10-6 whereas taking into account the FSI effects, this ratio could reach 10-4 and is at the same order as Lambdac -> n pi0. Concrete values depend on phenomenological parameters adopted in the calculations. These branching ratios can be measured in the experiments to come.
