We report the first observation of the radiative charm decay $D^0 \to \gamma \omega$ with a significance of $6.0\sigma$. The analysis uses 20.3\,$\rm{fb}^{-1}$ of $e^+e^-$ collision data collected by the BESIII detector at a center-of-mass energy of 3.773\,GeV, and employs a deep learning strategy based on the Particle...

Based on an integrated luminosity of $20.3~\mathrm{fb}^{-1}$ of $e^{+}e^{-}$ annihilation data collected at a center-of-mass energy of $3.773~\rm{GeV}$ with the BESIII detector operating at the BEPCII collider, an improved search for the radiative transitions $\psi(3770) \to \gamma \eta_{c}(1S, 2S)$ is performed using...

Using a data sample corresponding to an integrated luminosity of 43.8~fb$^{-1}$ collected with the \mbox{BESIII} detector at 44 center-of-mass energy points between 3.510 and 4.946~GeV, the Born cross sections for the process $e^+e^- \to p \bar{n} \pi^-$ and its charge-conjugated process are measured. The energy depend...

We perform a simultaneous amplitude analysis of the decays $D^0 \to K_{\text{S}}^{0}\pi^{+}\pi^{-}$ and $D^0 \to K_{\text{L}}^{0}\pi^{+}\pi^{-}$ using an $e^+e^-$ collision data sample, corresponding to an integrated luminosity of $20.3\,\text{fb}^{-1}$, collected at the centre-of-mass energy of $3.773\,\text{GeV}$ wit...

Using $e^+e^-$ collision data collected by the BESIII detector at BEPCII corresponding to a total integrated luminosity of 44.6 $\rm fb^{-1}$, we present the first measurement of the Born cross sections for the process $e^+e^-\to pK^{-}\bar{\Sigma}^{0}$ + c.c. at fifty-six center-of-mass energies between 3.51 and 4.95~...

Using $2712.4 \pm 14.3$ million $\psi(3686)$ events collected with the BESIII detector, the $\Lambda\bar{\Lambda}$ system produced in $\psi(3686)$ radiative decays is studied. A model-independent partial wave analysis reveals a significant threshold enhancement structure dominated by the $^1S_0$ and $^3P_0$ partial wav...

Using $e^+e^-$ collision data samples collected with the BESIII detector at the BEPCII at center-of-mass energies between 3.510 and 4.951 GeV corresponding to an integrated luminosity of 44.55 fb$^{-1}$, the Born cross sections of the processes $e^+e^- \to K_S^0 \bar{\Xi}^0 \Lambda/\Sigma^0+\text{c.c.}$ are measured wi...

Based on a data sample of 10 billion $J/\psi$ events collected with the BESIII detector operating at the BEPCII collider, the Dalitz decay $\Sigma^0 \rightarrow \Lambda e^+e^-$ is studied experimentally for the first time. The $\Sigma^0$ hyperons are produced through the process $J/\psi \rightarrow \Sigma^0\bar{\Sigma}...
