First Observation of \boldmath{ $D^{+} \to a_{0} (980) ρ$ and $D^{+} \to a_{0} (980)^{+} f_{0} (500)$ } in \boldmath{ $D^{+} \to π^{+} π^{+} π^{-} η$ and $D^{+} \to π^{+} π^{0} π^{0} η$ } Decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +756

We perform the first amplitude analysis of the singly Cabibbo-suppressed decays $D^{+} \to π^{+} π^{+ (0)} π^{- (0)} η$ , using $e^{+} e^{-}$ collision data collected with the BESIII detector…

Measurement of the branching fractions of $χ_{c J} \to π^{+} π^{-} π^{0} π^{0}$ via $ψ (3686) \to γ χ_{c J}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +762

Using $(2712.4 \pm 14.3) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector operating at BEPCII, the branching fractions of $χ_{c J} \to π^{+} π^{-} π^{0} π^{0}$ ( $J = 0, 1, 2$ ) are mea…

Measurement of the singly Cabibbo-suppressed decay $Λ_{c}^{+} \to p η^{'}$ with Deep Learning

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Using $4.5$ fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected with the BESIII detector at center-of-mass energies from 4.600 to 4.699 GeV, we report a measurement of the singly Cabibb…

Measurement of the hyperon weak radiative decay $Ξ^{0} \to γ Σ^{0}$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

The hyperon weak radiative decay $Ξ^{0} \to γ Σ^{0}$ is measured via the process $J / ψ \to Ξ^{0} Ξ ˉ^{0}$ . The absolute branching fraction of $Ξ^{0} \to γ Σ^{0}$ is determined to be $(3.69\pm 0.21_{\t…
