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…

BESIII Collaboration, M. Ablikim, M. N. Achasov +596

By analyzing 7.33 fb $^{- 1}$ of $e^{+} e^{-}$ annihilation data collected at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, we report the observation of th…

Search for the production of deuterons and antideuterons in e^+e^- annihilation at center-of-mass energies between 4.13 and 4.70 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +603

Using a data sample of $e^{+} e^{-}$ collision data corresponding to an integrated luminosity of 19 fb $^{- 1}$ collected with the BESIII detector at the BEPCII collider, we search for th…
