$B \to \pi^+ \pi^-, K \pi, K \etap$ decays and new physics effects in   the general two-Higgs-doublet model: an update
  In this paper, we reexamine the new physics contributions to seven well measured $B \to PP$ decays in the standard model (SM) and the general two-Higgs-doublet model (model III) and compare the theoretical predictions with the new data. Within the considered parameter space we found that: (a) the measurements of the branching ratios for $B\to \pi^+ \pi^-, K^- \pi^+$ and $K^0 \pi^+$ lead to a strong constraint on the form factor $F_0^{B\pi}(0)$: $F_0^{B\pi}(0)=0.24 \pm 0.03$; (b) the new physics enhancements to the penguin-dominated $B \to K \pi$ and $K \etap$ decays are significant in size, $\sim (40-65)%$ $w.r.t$ the SM predictions, and play an important role in restoring the consistency between the data and the theory.
