SU(3) symmetry and its breaking effects in semileptonic heavy baryon decays
We employ the flavor SU(3) symmetry to analyze semileptonic decays of anti-triplet charmed baryons (Λc+,Ξc+,0) and find that the experimental data on B(Λc→Λℓ+νℓ) implies B(Ξc0→Ξ−e+νe)=(4.10±0.46)% and B(Ξc0→Ξ−μ+νμ)=(3.98±0.57)%. When this prediction is confronted with recent experimental results fro...
