Abstrak

Abstract Nonleptonic and semileptonic decay widths of $${\Lambda _b} \rightarrow {\Lambda _c}$$ Λb→Λc are analyzed within heavy quark limit and Isgur-Wise formalism. A modified QCD Cornell interaction with the additional logarithmic term in the hyperspherical coordinates is considered and the masses of heavy flavour baryons are calculated. The obtained masses are consequently employed to study the rates of $${\Lambda _b} \rightarrow {\Lambda _c}$$ Λb→Λc . The achieved results are motivating.
