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
We perform the first amplitude analysis of D_{s}^{+}→π^{+}π^{+}π^{-}π^{0} decays based on data samples electron-positron collisions recorded with BESIII detector at center-of-mass energies between 4.128 and 4.226 GeV, corresponding to an integrated luminosity 7.33 fb^{-1}. report observation D_{s}^{+}→f_{0}(980)ρ(770)^{+} a statistical significance greater than 10σ determine branching fractions B(D_{s}^{+}→π^{+}π^{+}π^{-}π^{0}|_{non-η})=(2.04±0.08_{stat}±0.05_{syst})%...
