Measurements of absolute branching fractions of $D^{0 (+)} \to K K K π$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +697

Using an $e^{+} e^{-}$ sample of $20.3 f b^{- 1}$ collected at the center-of-mass energy $s =$ 3.773 GeV with the BESIII detector, we report measurements of several four-body h…

Study of $η \to π^{+} π^{-} l^{+} l^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +639

Using a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events accumulated with the BESIII detector, we analyze the decays $η \to π^{+} π^{-} l^{+} l^{-}$ ( $l = e$ or $μ$ ) via the process $J/ψ…
