The branching fraction ratios between the charged and neutral modes are consistent with the prediction of isospin symmetry.eninfo:eu-repo/semantics/openAccessImproved measurements of X-cJ -> Sigma(+) (Sigma)over-bar(-) and Sigma(0)(Sigma)over-bar(0) decaysArticle2-s2.0-8504485459010.1103/PhysRevD.97.052011Q1WOS:000428505700001
