We present a new determination of the smallest neutrino mixing angle θ_{13} and mass-squared difference Δm_{32}^{2} using final sample 5.55×10^{6} inverse beta-decay (IBD) candidates with final-state neutron captured on gadolinium. This is selected from complete dataset obtained by Daya Bay reactor experiment in 3158 days operation. Compared to previous results, selection IBD has been optimized, energy calibration refined, treatment backgrounds further improved. The resulting oscillation...
Based on $5.8 \times 10^7 J\psi$ events collected with BESII at the Beijing Electron-Positron Collider (BEPC), decay branching fractions of $J\psi\to\omega\pi^0$, $\omega\eta$, and $\omega\eta'$ are measured using different $\eta$ $\eta'$ modes. The results higher than previous measurements. $\omega\pi^0$ electromagnetic form factor is also obtained.
ACTS has been used as a tracking toolkit at experiments such ATLAS, sPHENIX, FASER, ALICE, etc. and shown very promising performance in terms of both physics time performance. So far, the applications are mainly focusing on silicon-based systems. However, its application for Beijing Spectrometer (BESIII) gaseous detectors, example, drift chamber, is limited. The extension chambers two future electron–positron collision experiments, i.e. Circular Electron Positron Collider (CEPC) Super Tau...
