The study of weak decays induced by [Formula presented] transition in light-cone sum rules
Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2023-12-10)
In this study, we analyzed the weak decays induced by [Formula presented] transitions within the light-cone sum rules. Specifically, semileptonic decays of the bottom baryons into the P-wave baryons Λb→Λc(2625)ℓνl and Ξb→Ξ...
