| Description: |
We study the semileptonic decay of its SU(3) partner, the Λc→Λℓ+νℓ (ℓ=e,μ) transition, within the framework of light-cone QCD sum rules (LCSR) by using the distribution amplitudes of heavy Λc baryon. The numerical analysis is performed using two different sets of Λc baryon light-cone distribution amplitudes. The resulting form factors are parametrized by a model-independent z-series expansion and used to compute the differential and total decay widths. Our predictions for the branching fractions are in good agreement with the latest BESIII measurements and with lattice-QCD results. |
