Observation of $\hat{I}\text{c◯}(2012{)}^{-}\to \hat{I}ž(1530)\bar{K}$ and measurement of the effective couplings of $\hat{I}\text{c◯}(2012{)}^{-}$ to $\hat{I}ž(1530)\bar{K}$ and $\hat{I}ž\bar{K}$

Using $\hat{I}\yen (1S)$, $\hat{I}\yen (2S)$, and $\hat{I}\yen (3S)$ data collected by the Belle detector, we discover a new three-body decay, $\hat{I}\text{c◯}(2012{)}^{-}\to \hat{I}ž(1530)\bar{K}\to \hat{I}ž\ddot{I}€\bar{K}$, with a significance of…
