First Measurement of the Decay Dynamics in the Semileptonic Transition of the $D^{+ (0)}$ into the Axial-vector Meson $K ˉ_{1} (1270)$

BESIII Collaboration, M. Ablikim, M. N. Achasov +677

Using $e^{+} e^{-}$ data taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, corresponding to an integrated luminosity of 20.3 fb $^{- 1}$ , we report the first measu…

Study of the electromagnetic Dalitz decay $J / ψ \to e^{+} e^{-} π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +640

We report the first measurement of the di-electron invariant mass dependent transition form factor in the electromagnetic Dalitz decay $J / ψ \to e^{+} e^{-} π^{0}$ using $(10087 \pm 44) \ti…

Observation of $χ_{c J} \to p p ˉ K_{S}^{0} K^{-} π^{+} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +653

By analyzing $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decays of $χ_{cJ} \to p \bar{p} K^0_S K^- π^+ +c.c…
