| Description: |
We present a light-cone QCD sum rule (LCSR) analysis of the semileptonic decays of Ξc baryons, focusing on the channels Ξ0c → Ξ−lþνl, and Ξþc → Ξ0lþνl. The transition form factors are calculated within the light-cone quantum chromodynamics (QCD) sum rules framework, using the distribution amplitudes of the heavy Ξc baryons. The obtained form factors are then used to compute the differential and total decay widths, as well as the branching fractions. Our numerical results for the branching fractions are BðΞ0c →Ξ−lþνlÞ¼ð3.73±1.04Þ%, BðΞ0c →Ξ−μþνμÞ¼ð3.59±1.01Þ%, BðΞþc →Ξ0lþνlÞ¼11.2±3.25Þ%, and BðΞþc → Ξ0μþνμÞ ¼ ð10.8 ± 3.13Þ%. These results are in good agreement with recent lattice QCD calculations, while being larger than the current experimental measurements and differing from the predictions of other theoretical approaches. |
