First Measurement of the Absolute Branching Fraction of $η_{c} \to γ γ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +691

We apply a tag-and-probe method to precisely measure the absolute branching fraction of the decay $η_{c} \to γ γ$ with the BESIII experiment at BEPCII. Starting with a large initial s…

Determination of U-spin breaking parameters with an amplitude analysis of the decay $D^{0} \to K_{L}^{0} π^{+} π^{-}$

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

We present a study of the resonant structure of the decay $D^{0} \to K_{L}^{0} π^{+} π^{-}$ , using quantum-correlated $D^{0} D ˉ^{0}$ data produced at $s = 3.773$ GeV. The data sampl…

Search for the weak radiative decay $Λ_{c}^{+} \to Σ^{+} γ$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +567

The Cabibbo-allowed weak radiative decay $Λ_{c}^{+} \to Σ^{+} γ$ has been searched for in a sample of $Λ_{c}^{+} Λ ˉ_{c}^{-}$ pairs produced in $e^{+} e^{-}$ annihilations, corresponding to an i…

Amplitude analysis and branching fraction measurement of the decay $D_{s}^{+} \to K^{+} π^{+} π^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +560

Using $6.32$ fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected at the center-of-mass energies between 4.178 and 4.226 GeV with the BESIII detector, we perform an amplitude analysi…
