Evidence of $I ¨ (3770) \to I ¨ ^{0} J / I ¨ $

BESIII Collaboration, M. Ablikim, M. N. Achasov +766

We report the first evidence for the hadronic transition $I ¨ (3770) \to I ¨ ^{0} J / I ¨ $ using a data sample of $20.3 fb^{- 1}$ collected at $s = 3.773$ ~GeV with the BESIII…

Observation of a Doubly-strange Hyperon $I^ (1720)$ in $J / I ¨ \to K^{-} I^£^{0} I^ˉ ^{+} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +758

Based on a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events collected with the BESIII detector at BEPCII, we report the first observation of the decay $J/Ï\rightarrow K^- Î£^0…

Improved measurement of absolute branching fraction of the inclusive decay $I^_{c}^{+} \to K_{S}^{0} X$

BESIII Collaboration, M. Ablikim, M. N. Achasov +676

By analyzing $4.5$ fb $^{- 1}$ of $e^{+} e^{-}$ collision data accumulated with the BESIII detector at center-of-mass energies ranging from $4599.53$ MeV to $4698.82$ MeV, we report t…

Measurement of Born cross sections of $e^{+} e^{-} \to I^^{0} I^ˉ ^{0}$ and search for charmonium(-like) states at $s$ = 3.51-4.95 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +653

Using $e^{+} e^{-}$ collision data collected by the BESIII detector at BEPCII corresponding to an integrated luminosity of 30 $f b^{- 1}$ , we measure Born cross sections and effective…
