${{\mathit \Xi}_{{{c}}}^{+}}$ DECAY MODES

Branching fractions marked with a footnote, e.g. $\lbrack{}\mathit a$], have been corrected for decay modes not observed in the experiments. For example, the submode fraction ${{\mathit \Xi}_{{{c}}}^{+}}$ $\rightarrow$ ${{\mathit \Sigma}^{+}}{{\overline{\mathit K}}^{*}{(892)}^{0}}$ seen in ${{\mathit \Xi}_{{{c}}}^{+}}$ $\rightarrow$ ${{\mathit \Sigma}^{+}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ has been multiplied up to include ${{\overline{\mathit K}}^{*}{(892)}^{0}}$ $\rightarrow$ ${{\overline{\mathit K}}^{0}}{{\mathit \pi}^{0}}$ decays.
