Abstract：
Based on the assumption of a two-quark structure of the scalar meson f₀(980), we calculate the branching ratios and CP-violating asymmetries for the four B→ f₀(980)π and B→f₀(980)η^(′) decays by employing the perturbative QCD (pQCD) factorization approach. The leading order pQCD predictions for branching ratios are, Br(B^－→f₀(980)π^－)~2.5×10^－6, Br(B⁰→f₀(980)π⁰)~2.6×10^－7, Br(B⁰→f₀(980)η)~2.5×10^－7 and Br(B⁰→f₀(980)η′)~6.7×10^－7, which are consistent with both the QCD factorization predictions and the experimental upper limits.
