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…

Search for the charmonium weak decay $I ¨ (2 S) \to D_{s}^{-} I ¨ ^{+} + c . c .$ and $I ¨ (2 S) \to D_{s}^{-} I ¨ ^{+} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +720

We search for the weak decays $I ¨ (2 S) \to D_{s}^{-} I ¨ ^{+} + c . c .$ and $I ¨ (2 S) \to D_{s}^{-} I ¨ ^{+} + c . c .$ for the first time. The search is based on $(2712.4 \pm 14.3) \times 1 0^{6}$ events containin…

First Amplitude Analysis of $D^{0} \to K^{-} I ¨ ^{0} e^{+} I^½_{e}$ and Observation of $D^{0} \to K_{2}^{*} (1430)^{-} e^{+} I^½_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +687

We present the first amplitude analysis of the semileptonic decay $D^{0} \to K^{-} I ¨ ^{0} e^{+} I^½_{e}$ by analyzing $e^{+} e^{-}$ annihilation data corresponding to an integrated luminosity of…
