| dc.description | Two- and three-body decays of $Υ(5S)$ into $BB, $$ BB^*, $ $ B^*B^*,$ $ B_sB_s, $ $B_sB_s^*, $ $B_s^* B_s^*$ and $BB^*π, B^*B^*π$ are evaluated using the theory, developed earlier for dipion bottomonium transitions. The theory contains only two parameters, vertex masses $M_{br}$ and $M_ω$, known from dipion spectra and width. Predicted values of $Γ_{tot}(5S)$ and six partial widths $Γ_k(5S), k=BB, BB^*,...$ are in agreement with experiment. The decay widths $Γ_{5S}(πBB^*)$ and $Γ_{5S}(πB^*B^*)$ are also calculated and found to be of the order of 10 keV. | |
