TL;DR: An update of standard model predictions for the inclusive branching ratios of the B mesons is presented, incorporating all results for the O(α_{s}^{2}) and lower-order perturbative corrections that have been calculated after 2006.
Journal ArticleDOI
Flavor-phenomenology of two-Higgs-doublet models with generic Yukawa structure
TL;DR: In this article, an extensive study of flavor observables in a two-Higgs-doublet model with generic Yukawa structure was performed, where the free parameters of the model are the heavy Higgs mass, the ratio of vacuum expectation values, and the nonholomorphic Yukawa couplings.
Journal ArticleDOI
Improved model-independent analysis of semileptonic and radiative rare B decays
TL;DR: In this paper, the branching ratios for the B decays of the standard model and some variants of supersymmetric theories were updated and upper bounds on the Wilson coefficients were obtained.
