摘要:
Motivated by the observed forward-backward asymmetry in B → K*ℓ + ℓ − decay, we perform a detailed analysis of this decay mode within a family non-universal Z′ model. With the related coupling $$ Z' - \bar sb $$ constrained by $$ {B_s} - {\bar B_s} $$ mixing, B → πK and B → X s μ + μ − decays, we look for further constraint on the couplings Z′ − μ + μ − from $$ {A_{FB}}{\left( {B \to {K^*}{\mu^{+} }{\mu^{-} }} \right)_{0{\text{Ge}}{{\text{V}}^2} \leqslant {q^2} \leqslant 2{\text{Ge}}{{\te...
