Strong decays and dipion transitions of ϒ(5S)

Dipion transitions of ϒ(nS) with n=5, n′=1,2,3 are studied using the Field Correlator Method, applied previously to dipion transitions with n=2,3,4. The only two parameters of effective Lagrangian were fixed in that earlier study, and total widths Γππ(5,n′) as well as pionless decay widths ΓBB(5S), ΓBB∗(5S), ΓB∗B∗(5S) and ΓKK(5,n′) were calculated and are in a reasonable agreement with experiment. The experimental ππ spectra for (5,1) and (5,2) transitions are well reproduced taking into account FSI in the ππ.
