Measurement of the Inclusive Cross Sections of Prompt $J / I ¨ $ and $I ¨ (3686)$ Production in $e^{+} e^{-}$ Annihilation from $s = 3.808$ to $4.951$ GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +610

The inclusive cross sections of prompt $J / I ¨ $ and $I ¨ (3686)$ production are measured at center-of-mass energies from 3.808 to 4.951 GeV. The dataset used is 22 fb $^{- 1}$ of $e^{+}e…

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 the branching fraction and $CP$ -violating asymmetry of the decay $B^{0} \to I ¨ ^{0} I ¨ ^{0}$ using $387$ million bottom-antibottom meson pairs in Belle II data

Belle II Collaboration, I. Adachi, L. Aggarwal +437

We measure the branching fraction and $CP$ -violating flavor-dependent rate asymmetry of $B^{0} \to I ¨ ^{0} I ¨ ^{0}$ decays reconstructed using the Belle II detector in an electro…
