A direct evaluation of the Lambda_c^+ absolute branching ratios: a new approach

A novel method for a direct measurement of the exclusive Lambda_c^+ branching ratios is here described. The approach is based on the peculiar topology of the quasi-elastic charm neutrino-induced events on nucleons. The intrinsic potentiality of the method is thoroughly discussed using a "perfect detector". As an application, the statistical accuracy reachable with existing data sample has been estimated. From a theoretical point of view, such measurement provides a better understanding of the baryonic b-decays.
