Abstract

We present updated results of an SU(3)-flavor analysis of D->P P decay data including linear breaking and no further assumptions. The global fit is consistent with nominal (~ 30%) SU(3)F breaking and returns enhanced penguin (triplet) contributions. Their size is driven, in addition to Delta A_CP, by the CP asymmetries of D₀->K_S K_S, D_s->K_S pi⁺ and D_s->K⁺ pi⁰ decays. It is therefore especially important to improve these measurements.
