Description

We reconsider the mass insertion approximation in the limit in which the sfermions are highly non-degenerate. We show that the correlation between the supersymmetric contributions to Delta F = 1 and Delta F = 2 observables strongly depends on the sfermion spectrum. In particular, we show that larger contributions to the phase of the Bs mixing amplitude are allowed in the non-degenerate case.
