The fact that the measured B -> pi pi, pi K branching ratios exhibit puzzling patterns has received a lot of attention in the literature and motivated the formulation of a series of new physics scenarios with enhanced Z-penguins. Here, we analyze the effect of such an enhancement on the lepton polarization asymmetries of B-s -> gamma l(+)l(-) decays by applying the results of a specific scenario for the solution of "B - pi K puzzle".
