Hi,

I'm looking for the mass distribution dataset for the J/ψ→ϕπ+π− and ϕK+K− reactions measured by BES and described in this paper: Phys.Lett.B607:243-253,2005, arXiv:hep-ex/0411001 from 2005.

Unfortunately BES does not store their analyses in https://www.hepdata.net. I don't see any data available at their web site either. Perhaps somebody worked in this analysis and ha access to the published data sets ?

Generally any hints at data sets on 3 body decays where near threshold resonances in pi pi/KKbar like f0(980),pi eta like a0(980) or resonances DDbar system will be highly appreciated.
