Observation of $D^{+} \to f_{0} (500) I^¼^{+} I^½_{I^} ¼$ and study of $D^{+} \to I ¨ ^{+} I ¨ ^{-} ℓ^{+} I^½_{ℓ}$ decay dynamics

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

Using $2.93 fb^{- 1}$ of $e^{+} e^{-}$ collision data collected with the BESIII detector at the center-of-mass energy of 3.773 GeV,we investigate the semileptonic decays $D^+\to…

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.)…

Determination of spin-parity quantum numbers of X(2370) as $0^{-+}$ from $J / I ¨ \to I^^{3} K_{S}^{0} K_{S}^{0} I^\cdot^{'}$

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

Based on $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events collected with the BESIII detector, a partial wave analysis of the decay $J / I ¨ \to I^^{3} K_{S}^{0} K_{S}^{0} I^\cdot^{'}$ is perfo…
