Observation of the helicity-selection-rule suppressed decay of the $χ_{c 2}$ charmonium state

BESIII Collaboration, M. Ablikim, M. N. Achasov +424

The decays of $χ_{c 2} \to K^{+} K^{-} π^{0}$ , $K_{S} K^{\pm} π^{\mp}$ and $π^{+} π^{-} π^{0}$ are studied with the $ψ (3686)$ data samples collected with the Beijing Spectrometer (BESIII)…

Observation of the doubly radiative decay $η^{'} \to γ γ π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +426

Based on a sample of $1.31$ billion $J / ψ$ events collected with the BESIII detector, we report the study of the doubly radiative decay $η^{'} \to γ γ π^{0}$ for the first time, where…

Observation of $Λ_{c}^{+} \to n K_{S}^{0} π^{+}$

M. Ablikim, M. N. Achasov, S. Ahmed +424

We report the first direct measurement of decays of the $Λ_{c}^{+}$ baryon involving the neutron. The analysis is performed using 567 pb $^{- 1}$ of $e^{+} e^{-}$ collision data collected at…

Amplitude analysis of the $χ_{c 1} \to η π^{+} π^{-}$ decays

M. Ablikim, M. N. Achasov, S. Ahmed +430

Using $448.0 \times 1 0^{6}$ ~ $ψ (3686)$ events collected with the BESIII detector, an amplitude analysis is performed for $ψ (3686) \to γ χ_{c 1}$ , $χ_{c 1} \to η π^{+} π^{-}$ decays. The most domin…
