Based on 4.4 fb−1 of e+e− annihilation data collected at the center-of-mass energies between 4.60 and 4.70 GeV with BESIII detector BEPCII collider, pure W-boson-exchange decay Λc+→Ξ0K+ is studied a full angular analysis. The corresponding asymmetry measured for first time to be αΞ0K+=0.01±0.16(stat)±0.03(syst). This result reflects noninterference effect S- P-wave amplitudes. phase shift amplitudes has two solutions, which are δp−δs=−1.55±0.25(stat)±0.05(syst) rad or...
Influence maximization (IM) is crucial for recommendation systems and social networks. Previous research primarily focused on static networks, neglecting the homophily dynamics inherent in real-world This has led to inaccurate simulations of information spread influence propagation between nodes, with traditional IM algorithms’ selected seed node sets failing adapt network evolution. To address this issue, paper proposes a homophilic dynamic strategy based independent cascade model (HDIM)....

We present a measurement of the azimuthal asymmetries two charged pions in inclusive process e^{+}e^{-}→ππX, based on data set 62 pb^{-1} at center-of-mass energy 3.65 GeV collected with BESIII detector. These can be attributed to Collins fragmentation function. observe nonzero asymmetry, which increases increasing pion momentum. As our scale is close that existing semi-inclusive deep inelastic scattering experimental data, measured are important inputs for global analysis extracting quark...
Using 1.09×10^{9} J/ψ events collected by the BESIII experiment in 2012, we study J/ψ→γη^{'}π^{+}π^{-} process and observe a significant abrupt change slope of η^{'}π^{+}π^{-} invariant mass distribution at proton-antiproton (pp[over ¯]) threshold. We use two models to characterize line shape around 1.85 GeV/c^{2}: one that explicitly incorporates opening decay threshold spectrum (Flatté formula), another is coherent sum resonant amplitudes. Both fits show almost equally good agreement with...
