Rare $B\to K^{\ast }\nu \bar{\nu }$ decay with polarized $K^{\ast }$ in the fourth generation model

The rare $B\to K^{\ast }\nu \bar{\nu }$ decay when $K^{\ast }$ meson is longitudinally or transversely polarized is analysed in the context of the fourth generation model. A significant enhancement to the missing energy spectrum over the SM is recorded.
