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…

Observation of $I^ˉ p \to K^{+} I ¨ ^{+} I ¨ ^{-} I ¨ ^{0}$ and $I^ˉ p \to K^{+} I ¨ ^{+} I ¨ ^{-} 2 I ¨ ^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +750

Using $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events collected with the BESIII detector at a center-of-mass energy of $s = 3.097$ GeV, the antihyperon-nucleon annihilation process…

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…
