Abstract: Using a 3.19 fb^{-1} data sample collected at an e^{+}e^{-} center-of-mass energy of E_{cm}=4.178 GeV with the BESIII detector, we measure the branching fraction of the leptonic decay D_{s}^{+}→μ^{+}ν_{μ} to be B_{D_{s}^{+}→μ^{+}ν_{μ}}=(5.49±0.16_{stat}±0.15_{syst})×10^{-3}. Combining our branching fraction with… read more here.

DOI: 10.1109/tps.2024.3458449
Abstract: This study investigates the phenomenon of exploding wire (EW), focusing on the decrease in electrical current during the dark pause (dp) in copper filament explosions in atmospheric air. An exponential model is proposed to describe… read more here.
