First energy scan measurement of $e^{+} e^{-} \to K^{+} K^{-}$ around the $I ¨ (2 S)$ resonance

BESIII Collaboration, M. Ablikim, M. N. Achasov +684

We report the precise energy scan measurement of the cross section lineshape of $I ¨ (2 S) \to K^{+} K^{-}$ . The analysis is based on $e^{+} e^{-}$ collision data corresponding to an int…

Amplitude analysis and branching fraction measurement of the decay $D^{0} \to K^{+} K^{-} I ¨ ^{0} I ¨ ^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +770

An amplitude analysis of the singly Cabibbo-suppressed decay $D^{0} \to K^{+} K^{-} I ¨ ^{0} I ¨ ^{0}$ is performed, for the first time, to determine the relative magnitudes and phases of differ…
