Study of the $f_{0} (980)$ and $f_{0} (500)$ Scalar Mesons through the Decay $D_{s}^{+} \to I ¨ ^{+} I ¨ ^{-} e^{+} I^½_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +605

Using $e^{+} e^{-}$ collision data corresponding to an integrated luminosity of 7.33~ $f b^{- 1}$ recorded by the BESIII detector at center-of-mass energies between 4.128 and 4.226~$…

Measurement of Branching Fractions for $I^_{c}^{+} \to n K_{S}^{0} I ¨ ^{+}$ and $I^_{c}^{+} \to n K_{S}^{0} K^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +611

Based on 4.5 fb $^{- 1}$ of $e^{+} e^{-}$ collision data accumulated at center-of-mass energies between $4.600 GeV$ and $4.699 GeV$ with the BESIII detector, we me…

Search for di-photon decays of an axion-like particle in radiative $J / I ¨ $ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +614

We search for the di-photon decay of a light pseudoscalar axion-like particle, $a$ , in radiative $J / I ¨ $ decays, using 10 billion $J / I ¨ $ events collected with the BESIII detector. W…

Precision measurement of the branching fraction of \boldmath $J / I ¨ \to K^{+} K^{-}$ via $I ¨ (2 S) \to I ¨ ^{+} I ¨ ^{-} J / I ¨ $

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

Using a sample of $448.1 \times 1 0^{6}$ $I ¨ (2 S)$ events collected with the BESIII detector, we perform a study of the decay $J / I ¨ \to K^{+} K^{-}$ via $Ï(2S)\rightarrow Ï^+Ï^-J/…

Search for the leptonic decays $D^{+} \to e^{+} I^½_{e}$ and $D^{+} \to I^¼^{+} I^½_{I^} ¼$

BESIII Collaboration, M. Ablikim, M. N. Achasov +572

We present the first search for the leptonic decays $D^{*+} \to e^{+} I^½_{e}$ and $D^{*+} \to I^¼^{+} I^½_{I^} ¼$ by analyzing a data sample of electron-positron collisions recorded with the BESII…
