First Observation of a Three-Resonance Structure in $e^{+} e^{-} \to$ Nonopen Charm Hadrons

BESIII Collaboration, M. Ablikim, M. N. Achasov +619

We report the measurement of the inclusive cross sections for $e^{+} e^{-}$ $\to$ nOCH (where nOCH denotes non-open charm hadrons) with improved precision at center-of-mass (c.m.)…

Measurement of the absolute branching fraction of the three-body decay $I^_{c}^{+} \to I^^{0} K^{+} I ¨ ^{0}$ and search for $I^_{c}^{+} \to n K^{+} I ¨ ^{0}$ , $I^£^{0} K^{+} I ¨ ^{0}$ and $I^ K^{+} I ¨ ^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +611

The Cabbibo-favored decay $I^_{c}^{+} \to I^^{0} K^{+} I ¨ ^{0}$ is studied for the first time using 6.1 fb $^{- 1}$ of $e^{+} e^{-}$ collision data at center-of-mass energies between 4.600 and…

Observation of the Singly Cabibbo-Suppressed Decay $I^_{c}^{+} \to I^£^{-} K^{+} I ¨ ^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +616

The singly Cabibbo-suppressed decay $I^_{c}^{+} \to I^£^{-} K^{+} I ¨ ^{+}$ is observed for the first time with a statistical significance of $6.4 I ¨ $ by using 4.5 fb $^{- 1}$ of $e^{+} e^{-}$ c…
