摘要Motivated by the possible large annihilation contributions implied by recent CDF and LHCb measurements on nonleptonic annihilation B-meson decays, and the refined experimental measurements on hadronic B-meson decays, we study the strength of annihilation contributions within QCD factorization (QCDF) in this paper. With the available measurements of two-body B-u,B-d,B-s -> pi pi, pi K, KK decays, a comprehensive fit on the phenomenological parameters X-A(i,f) (or rho(i,f)(A) and phi(i,f)(A)) which are used to parameterize the endpoint singularity in annihilation amplitudes is performed with the statistical chi(2) approach. It is found that (1) flavor symmetry breaking effects are hardly to be distinguished between X-A,s(i) and X-A,d(i) due to the large experimental errors and theoretical uncertainties, where X-A,s(i) and X-A,d(i) are related to the nonfactorization annihilation contributions in B-s and B-u,B-d decay, respectively. So X-A,s(i) similar or equal to X-A,d(i) is a good approximation by now. (2) In principle, parameter X-A(f), which is related to the factorization annihilation contributions and independent of the initial state can be regarded as the same variable for B-u,B-d,B-s decays. (3) Numerically, two solutions are found, one is (rho(i)(A), phi(i)(A) [(o)]) = (2.98(-086)(+1.12) - 105(-24)(+34)) and (rho(f)(A), phi(f)(A) [(o)]) = (1.18(-0.23)(+0.20)), -40(-8)(+11)), the other is (rho(i)(A), phi(i)(A) [(o)]) = (2.97(-0.90)(+1.19), -105(-24)(+32) and (rho(f)(A), phi(f)(A) [(o)]) = (2.80(-0.21)(+0.25), 165(-3)(+4)). Obviously, nonfactorization annihilation parameter XiA is generally unequal to factorization annihilation parameter X-A(f), which differs from the traditional treatment. With the fitted parameters, all results for observables of B-u,B-d,B-s -> pi pi, pi K, KK decays are in good agreement with experimental data. (C) 2014 The Authors. Published by Elsevier B.V.
