Covariant tensor formalism for partial wave analyses of decays into
Sayipjamal Dulat, BoChao Liu, BingSong Zou +1
Recently BES2 collaboration observed an enhancement near the invariant mass spectrum. Using the covariant tensor formalism, here we provide theoretical formulae for the p…
Baryon Spectroscopy at Beijing Electron Positron Collider
B. S. Zou, X. B. Ji, H. X. Yang +1
BES Collaboration has collected 58 million events at the Beijing Electron-Positron Collider (BEPC). decays provide an excellent place for studying excited nucleons and…
N* Resonances in e+e- Collisions at Bepc
B. S. Zou, H. B. Li, representing BES Collaboration
particles are abundantly produced at the Beijing Electron Positron Collider (BEPC). The decays provide an excellent place for studying resonances. For $J/Ψ\to\bar…
pi-pi S-Wave Interaction and 0++ Particles
B. S. Zou
From a re-analysis of pi+ pi- -> pi+ pi- and pi+ pi- -> K K data, we found for pi-pi S-wave interaction below 2 GeV, sigma(400), f0(980), f0(1500) and f0(1780) clearly show up. f0(…
