Description

From the perspective that Λc(2595) and Λc(2625) are dynamically generated resonances from the DN, D*N interaction and coupled channels, we have evaluated the rates for Λb → π-Λc(2595) and Λb → π-Λc(2625) up to a global unknown factor that allows us to calculate the ratio of rates and compare with experiment, where good agreement is found. Similarly, we can also make predictions for the ratio of rates of the, yet unknown, decays of Λb → Ds-Λc(2595) and Λb → Ds-Λc(2625) and make estimates for their individual branching fractions.
