The BES experiment at the Beijing electron-positron collider has observed ξ(2230) signal in π+π−, K+K−, K0SK0S, and p¯p final states with 4.6σ, 4.1σ, 4.0σ, 3.8σ statistical significances, respectively. new observations of two nonstrange decay modes ξ→π+π− are important evidence for glueball interpretation ξ(2230).Received 30 October 1995DOI:https://doi.org/10.1103/PhysRevLett.76.3502©1996 American Physical Society
Railway catenary maintenance vehicles are essential for ensuring the safety and efficiency of electrified railway systems. The implementation pre-optimized speed profiles significantly reduces energy consumption while improving key operational performance metrics, such as ride comfort, punctuality, safety. This study introduces a novel multi-objective optimization method that optimizes profile in scenarios which performing operations on line sections. Initially, model is developed based...
The cross section for e+e−→ρπ has been measured by the BES detector at BEPC center-of-mass energies covering a 40 MeV interval spanning Jψ resonance. data are used to search vector gluonium state hypothesized Brodsky, Lepage, and Tuan as an explanation of ρπ puzzle in charmonium physics. shape is compatible with that total hadronic section. No distortions indicating presence glueball seen.Received 19 October 1995DOI:https://doi.org/10.1103/PhysRevD.54.1221©1996 American Physical Society
