Study of the Semileptonic decay Λc+ to Λe+νe
BESIII recently reported the study of the Cabibbo-favored Semileptonic (SL) decay Λc+ -> Λe+νe [Phys. Rev. Lett. 129, 231803 (2022)], with the largest Λc threshold data sets collected at the ce...

Precision measurements of hyperon radiative decay Λ → nγ
The BESIII collaboration has reported the first absolute branching fraction and decay asymmetry of Λ → nγ via J/ψ→ΛΛbar process with 10 billion J/ψ data. This is the first measurement of ra...

Observation of an Isoscalar Resonance with Exotic J^PC=1^(-+) Quantum Numbers in J/ψ→γηη'
