dc.descriptionDipion 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 $Γ_{ππ} (5, n')$ as well as pionless decay widths $Γ_{BB} (5S), Γ_{BB^*} (5S), Γ_{B^*B^*}(5S)$ and $Γ_{KK} (5, n')$ 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 $ππ$.
