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…

Search for a massless particle beyond the Standard Model in the $Ξ^{0} \to Λ + invisible$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +770

A search for a massless beyond-standard-model particle is performed in the decay $Ξ^{0} \to Λ + invisible$ using $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected with…
