dc.description.abstractUsing 2.93 fb(-1) of e(+) e(-) collision data taken at a center-of-mass energy of 3.773 GeV by the BESIII detector at the BEPCII, we measure the branching fractions of the singly Cabibbo-suppressed decays D -> omega pi pi to be B(D-0 -> omega pi(+) pi(-)) = (1.33 +/- 0.16 +/- 0.12) x 10(-3) and B(D+ -> omega pi(+)pi(0)) = (3.87 +/- 0.83 +/- 0.25) x 10(-3), where the first uncertainties are statistical and the second ones systematic. The statistical significances are 12.9 sigma and 7.7 sigma, respectively. The precision of B(D-0 -> omega pi(+) pi(-)) is improved by a factor of 2.1 over prior measurements, and B(D+ -> omega pi(+) pi(0)) is measured for the first time. No significant signal for D-0 -> omega pi(0)pi(0) is observed, and the upper limit on the branching fraction is B(D-0 -> omega pi(0)pi(0)) < 1.10 x 10(-3) at the 90% confidence level. The branching fractions of D -> eta pi pi are also measured and consistent with existing results.en_US
