  "abstract": "Using a coupled channel unitary approach, combining the heavy quark spin symmetry and the dynamics of the local hidden gauge, we investigate the meson-baryon interaction with hidden beauty and obtain several new states of $N^*$ around 11 GeV. We consider the basis of states $\\eta_b N$, $\\Upsilon N$, $B \\Lambda_b$, $B \\Sigma_b$, $B^* \\Lambda_b$, $B^* \\Sigma_b$, $B^* \\Sigma_b^*$ and find four basic bound states which correspond to $B \\Sigma_b$, $B \\Sigma_b^*$, $B^* \\Sigma_b$ and $B^* \\Sigma_b^*$, decaying mostly into $\\eta_b N$ and $\\Upsilon N$ and with a binding energy about 50-130 MeV with respect to the thresholds of the corresponding channel. All of them have isospin $I=1/2$, and there are no bound states or resonances in $I=3/2$. The $B \\Sigma_b$ state appears in $J=1/2$, the $B \\Sigma_b^*$ in $J=3/2$, the $B^* \\Sigma_b$ appears nearly degenerate in $J=1/2, ~3/2$ and the $B^* \\Sigma_b^*$ appears nearly degenerate in $J=1/2, ~3/2, ~5/2$. These states have a width from $6 \\sim 45 \\mev$ except for the one in $J=5/2$ which has zero width since it cannot decay into any of the states of the basis chosen.",
