We analyze exclusive cross sections in the $B\\bar{B}$, $B^* \\bar{B}(+c.c.)$, $B^*\\bar{B}^*$, $B_s^*\\bar{B}_s^*$, $\\Upsilon(nS)\\pi^+\\pi^-$ and $h_b(nP)\\pi^+\\pi^-$ channels as well as the total inclusive cross section for $b\\bar{b}$ production. Pole positions and residues are determined for four vector states, which we associate with the $\\Upsilon(4S)$, $\\Upsilon(10750)$, $\\Upsilon(5S)$ (or $\\Upsilon(10860)$), and $\\Upsilon(6S)$ (or $\\Upsilon(11020)$).
