The Production and Decay Dynamics of the Charmed Baryon $I^_{c}^{+}$ in $e^{+} e^{-}$ Annihilations near Threshold

BESIII Collaboration, M. Ablikim, M. N. Achasov +700

The study of the charmed baryons is crucial for investigating the strong and weak interactions in the Standard Model and for gaining insights into the internal structure of baryons…

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.)…

Study of excited $I^$ states in $I ¨ (3686) \to K^{-} I^ I^^{+} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +599

Based on a sample of $(448.1 \pm 2.9) \times 1 0^{6}$ $I ¨ (3686)$ events collected with the BESIII detector at BEPCII, the decays of $I ¨ (3686) \to K^{-} I^ I^^{+} + c . c .$ with $\o…

Observation of the Anomalous Shape of $X (1840)$ in $J / I ¨ \to I^^{3} 3 (I ¨ ^{+} I ¨ ^{-})$ Indicating a Second Resonance Near $p p ˉ$ Threshold

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

Using a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events, which is about 45 times larger than that was previously analyzed, a further investigation on the $J/Ï\rightarrow Î³3(Ï^…
