Observation of the Electromagnetic Dalitz Transition $h_{c} \to e^{+} e^{-} η_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +504

Using $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ decays and data samples of $e^{+} e^{-}$ collisions with $s$ from 4.130 to 4.780~GeV collected with the BESIII detector, we report the…

Search for $Λ ˉ$ - $Λ$ oscillations in the decay $J / ψ \to p K^{-} Λ ˉ + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +454

We report the first search for $Λ ˉ$ -- $Λ$ oscillations in the decay $J / ψ \to p K^{-} Λ ˉ + c . c .$ by analyzing $1.31 \times 1 0^{9}$ $J / ψ$ events accumulated with the BESIII detector at…

First Observation of the Direct Production of the $χ_{c 1}$ in $e^{+} e^{-}$ Annihilation

BESIII Collaboration

We study the direct production of the $J^{P C} = 1^{++}$ charmonium state $χ_{c 1} (1 P)$ in electron-positron annihilation by carrying out an energy scan around the mass of the $χ_{c1}(…
