These observables are constructed as ratios of U-spin related decays based on $B_{d,s}^0\\rightarrow {K^{(*)0}\\bar K^{(*)0}}$. The model gives a one-loop contribution to the Wilson coefficient of the chromomagnetic dipole operator needed to explain the tension in both non-leptonic observables, while naturally avoiding large contributions to the corresponding electromagnetic dipoles.
