The study of B→K(*)l+l- decays in family non-universal Z' models

  • In a combined investigation of B→K(*)l+l- decays, constraints on the related couplings in family non-universal Z' models are derived. We find that within the allowed parameter space, the recently observed forward-backward asymmetry in the B→K(*)l+l- decay can be explained by flipping the signs of the Wilson coefficients C9eff and C10. With the obtained constraints, we also calculate the branching ratio of the Bs→μ+μ- decay. The upper bound of our prediction is nearly an order of magnitude smaller than the upper bound given by the CDF Collaboration recently.

The study of B→K(*)l+l- decays in family non-universal Z' models

Abstract: In a combined investigation of B→K(*)l+l- decays, constraints on the related couplings in family non-universal Z' models are derived. We find that within the allowed parameter space, the recently observed forward-backward asymmetry in the B→K(*)l+l- decay can be explained by flipping the signs of the Wilson coefficients C9eff and C10. With the obtained constraints, we also calculate the branching ratio of the Bs→μ+μ- decay. The upper bound of our prediction is nearly an order of magnitude smaller than the upper bound given by the CDF Collaboration recently.
