Analysis of factors influencing the degree of accidental injury of bicycle riders considering data heterogeneity and imbalance Open
Bicycle safety has emerged as a pressing concern within the vulnerable transportation community. Numerous studies have been conducted to identify the significant factors that contribute to the severity of cyclist injuries, yet the findings…

Measurement of absolute branching fractions of $D_s^+$ hadronic decays Open
Using $e^+ e^-$ collision data collected at the BESIII detector at center-of-mass energies between 4.128 and 4.226 GeV, corresponding to an integrated luminosity of $7.33~{\rm fb}^{-1}$, we determine the absolute branching fractions of fif…

Observation of $ψ(3686) \to Ω^- K^+ \barΞ^0 $+c.c Open
Using $(27.12 \pm 0.14) \times 10^{8}$ $ψ(3686)$ events collected with the BESIII detector at BEPCII, the decay of $ψ(3686) \to Ω^- K^+ \barΞ^0 +c.c.$ is observed for the first time. The branching fraction of this decay is measured to be $…

Research and Deduction of Car-to-TW Vehicle AEB Test Scenarios Based on Improved Clustering Methods Open
Two-wheeled (TW) vehicle accidents are one of the major types of urban traffic accidents. TW cyclists who lack safety protection usually suffer more serious injuries and deaths in collisions. Developments in automotive active safety techno…

Helicity amplitude analysis of $χ_{cJ} \rightarrow ϕϕ$ Open
Using (447.9 $\pm$ 2.3) million $ψ$(3686) events collected with the BESIII detector, the decays of $χ_{cJ} \rightarrow ϕϕ$ ($J$=0, 1, 2) have been studied via the decay $ψ(3686)\rightarrowγχ_{cJ}$. The branching fractions of the decays $χ_…

Measurement of the $e^+e^-\toπ^+π^-J/ψ$ cross section in the vicinity of 3.872 GeV Open
We report a measurement of the cross section for the process $e^+e^-\toπ^+π^-J/ψ$ around the $X(3872)$ mass in search for the direct formation of $e^+e^-\to X(3872)$ through the two-photon fusion process. No enhancement of the cross sectio…

Study of the Semileptonic Decay $Λ_c^+\rightarrow Λe^+ν_e$ Open
The measurement of the Cabibbo-favored semileptonic decay $Λ_c^+\rightarrow Λe^+ν_e$ is reported using a $4.5~\mathrm{fb}^{-1}$ data sample of $e^+e^-$ annihilations collected at center-of-mass energies ranging from 4.600~GeV to 4.699~GeV …

Measurement of the total and leptonic decay widths of the $J/ψ$ resonance with an energy scan method at BESIII Open
Using $e^+e^-$ annihilation data sets collected with the BESIII detector, we measure the cross sections of the processes $e^+e^- \to e^+e^-$ and $e^+e^- \to μ^+μ^-$ at fifteen center-of-mass energy points in the vicinity of the $J/ψ$ reson…
