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…

Measurement of $C P$ asymmetries in $B^{0} \to I^\cdot^{'} K_{s}^{0}$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +399

We describe a measurement of charge-parity ( $C P$ ) violation asymmetries in $B^{0} \to I^\cdot^{'} K_{S}^{0}$ decays using Belle II data. We consider $I^\cdot^{'} \to I^\cdot (\to I^^{3} I^^{3}) I ¨ ^{+} I ¨ ^{-}$ and $Î·'\toÏ(\toÏ^…

Search for $h_{b} (2 P) \to I^^{3} I ¨ _{b J} (1 P)$ at $s = 10.860$ GeV

Belle Collaboration, A. Boschetti, R. Mussa +140

In the bottomonium sector, the hindered magnetic dipole (M1) transitions between P-wave states $h_{b} (2 P) \to I ¨ _{b J} (1 P) I^^{3}$ , $J = 0, 1, 2$ , are expected to be severely…
