  "abstract": "We analyze the CP asymmetries of $B\\to \\phi K$ and $B\\to \\eta^{(\\prime)} K$ modes in the QCD improved factorization framework. For our calculation we use the phenomenological parameters predetermined from the global fit for the available $B\\to PP$ and $VP$ modes (without the quark-level subprocess $b\\to s\\bar s s$). We show that the large negative $\\sin (2\\phi_1)_{\\phi K_s}$ and the large branching ratio for $B^{\\pm}\\to \\eta' K^{\\pm}$ can be simultaneously explained in the context of supersymmetry (SUSY). The R-parity conserving SUGRA models are used and their parameter space is constrained with the observed dark matter relic density along with other experimental constraints. The R-parity violating SUSY models are also used to show that they can provide solutions. We calculate the CP asymmetries for different $B^{\\pm (0)} \\to \\phi K^{\\pm (0)}$ and $B^{\\pm (0)} \\to \\eta^{(')} K^{\\pm (0)}$ modes and show that the SUSY model predictions are consistent with the available experimental data.",
