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/…

Measurement of $e^{+} e^{-} \to I ¨ I^\cdot^{'}$ cross sections at $s =$ 2.000 to 3.080 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +610

The Born cross sections for the process $e^{+} e^{-} \to I ¨ I^\cdot^{'}$ are measured at 22 center-of-mass energies from 2.000 to 3.080 GeV using data collected with the BESIII detect…
