Strong and electromagnetic amplitudes, direct $C P$ and isospin asymmetries in the decays $J / I ¨ \to K_{S}^{0} K^{+} I ¨ ^{-} + c . c .$

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

Using $e^{+} e^{-}$ annihilation data collected at 26 center-of-mass energy points between 3000.00 and $3119.88 MeV$ with the BESIII detector, corresponding to a total integrated…

Unexpected large relative strong phase and search for isospin breaking and $C P$ asymmetries in $J/Ï\to K^*(892)\bar K

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

Using a direct scan of 26 energy points near the $J / I ¨ $ resonance, we perform the first measurement of the relative phase $I ¨ _{I^^{3}, 3 g}$ between the strong and electromagnetic ampli…

Study of $I ¨ \to K K ˉ$ in the amplitude analysis of $D^{+} \to K_{S}^{0} K_{L}^{0} I ¨ ^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +772

We present the first amplitude analysis and branching fraction measurement of $D^{+} \to K_{S}^{0} K_{L}^{0} I ¨ ^{+}$ decay. The analysis uses a dataset corresponding to an in…

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…
