We measure the mass difference between $D_{s}^{*+}$ and $D_{s}^{+}$, $Δm_s$, using the decay chain $D_{s}^{*+} \to D_{s}^{+}(\to K^{+} K^{-} π^{+})π^{0}$, utilizing $e^+e^-$ annihilation data corresponding to an integrated luminosity of 3.19 fb$^{-1}$ collected at a center-of-mass energy of 4.178 GeV with the …

First measurements of the branching fractions of $J/ψ\to Ξ^0\barΛK^0_S+c.c.$, $J/ψ\to Ξ^0\barΣ^0 K^0_S+c.c.$, and $J/ψ\to Ξ^0\barΣ^- K^++c.c.$

BESIII Collaboration, M. Ablikim, Mikhail N. Achasov, P. Adlarson et autres

By analyzing $(10087 \pm 44)\times10^6$ $J/ψ$ events collected with the BESIII detector at the BEPCII, the decays $J/ψ\to Ξ^0\barΛK^0_S+c.c.$, $J/ψ\to Ξ^0\barΣ^0 K^0_S+c.c.$, and $J/ψ\to Ξ^0\barΣ^- K^++c.c.$ are observed for the first time. Their branching fractions are determined to be $\mathcal{B}(J/ψ\to Ξ^0\barΛK^0_S+c.c.)=(3.76\pm 0.14\pm …

Age of Information-Aware Multi-Objective Optimization for Heterogeneous UAV-USV-UUV Networks in Underwater Target Hunting

Xiangwang Hou, T. Y. Xing, Jun Du, Chunxiao Jiang et autres

Underwater target hunting (UTH) is a critical and complex mission involving the search, monitoring, and hunting of targets in an underwater environment. However, the unpredictable trajectories and flexibility of these targets, along with complex underwater environments, significantly impede the efficiency and success …

Observation of $χ_{cJ}(J=0,1,2)\rightarrow p\bar{p}ηη$

BESIII Collaboration, Mikhail N. Achasov, P. Adlarson, X. Ai et autres

Using $(2712.4\pm14.3)\times10^6$ $ψ(3686)$ events collected by the BESIII detector operating at the BEPCII storage ring, the decays $χ_{cJ}(J=0,1,2)\rightarrow p\bar{p}ηη$ are observed for the first time through the radiative transition $ψ(3686)\toγχ_{cJ}$. The statistical significances for $χ_{cJ}$ signals are all larger than 5$σ$. The …
