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…

Amplitude Analysis of the Isospin-Violating Decay $J / I ¨ \to I^^{3} I^\cdot I ¨ ^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +759

Using $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events collected with the BESIII detector, we perform the first amplitude analysis of the process $J / I ¨ \to I^^{3} I^\cdot I ¨ ^{0}$ . The decay is domina…

Search for the radiative decays $D^{0} \to I^^{3} K ˉ_{1} (1270)^{0}$ and $D^{+} \to I^^{3} K_{1} (1270)^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +680

A search for the radiative decays $D^{0} \to I^^{3} K ˉ_{1} (1270)^{0}$ and $D^{+} \to I^^{3} K_{1} (1270)^{+}$ is conducted using $20.3 fb^{- 1}$ of $e^{+} e^{-}$ annihilation data collected at the c…
