Abstract: In the framework of the topcolor-assisted technicolor $TC2$ model and thelittlest Higgs model with $T$-parity $LHT$ model, we consider the rare Bdecays $B\to M u\bar{ u}$ with $M=\pi,K, ho,$ or $K^{\ast}$. We find thatthe contributions of the $TC2$ model to the branching ratios of these decayprocesses are larger than those for the $LHT$ model. The experimental upperlimits for some branching ratios can give severe constraints on the freeparameters of the $TC2$ model.
