SU(3)F in nonleptonic charm decays

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 D_0->K_S K_S, D_s->K_S pi^+ and D_s->K^+ pi^0 decays. It is therefore especially important to improve these measurements.
