First Observation and Dynamical Study of the $D^+_s\to f_{0}(980) \mu^+\nu_\mu$ Decay

Using 7.33 fb$^{-1}$ of $e^+e^-$ annihilation data recorded with the BESIII detector at center-of-mass energies from 4.128 to 4.226 GeV, we report the first observation and dynamical study of the semileptonic decay $D^+_s\to f_{0}(980) \mu^+\nu_\mu$. The absolute branching fraction of $D^+_s\to f_{0}(980) \mu^+\nu_\mu$...

Measurement of the cross sections of $e^+e^-\to K_{S}^{0}\bar\Xi^{0}\Lambda/\Sigma^{0} + \text{c.c.}$ at center-of-mass energies between 3.510 and 4.951 GeV

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...

Measurement of Branching Fraction and Transition Magnetic Moment of the Hyperon Dalitz Decay $\Sigma^0 \rightarrow \Lambda e^+e^-$

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}...
