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

Belle Collaboration, S. Jia, C. P. Shen +117

Using $I^¥ (1 S)$ , $I^¥ (2 S)$ , and $I^¥ (3 S)$ data collected by the Belle detector, we discover a new three-body decay, $I^c ◯ (2012)^{-} \to I^ (1530) K ˉ \to I^ I ¨ K ˉ$ , with a significance of…
