dc.description.abstractBy analyzing e(+)e(-) annihilation data corresponding to an integrated luminosity of 2.93 fb(-1) collected at the center-of-mass energy of 3.773 GeV with the BESIII detector, we report the first observations of the doubly Cabibbo-suppressed decays D+ -> K+ pi(0)pi(0) and D+ -> K+ pi(0)eta. The branching fractions of D+ -> K+ pi(0)pi(0) and D+ -> K+ pi(0)eta are measured to be (2.1 +/- 0.4(stat) +/- 0.1(syst)) x 10(-4) and (2.1 +/- 0.5(stat) +/- 0.1(syst)) x 10(-4) with statistical significances of 8.8 sigma and 5.5 sigma, respectively. In addition, we search for the subprocesses D+ -> K*(892)(+)pi(0) and D+-> K*(892)(+)eta with K*(892)(+) -> K+pi(0). The branching fraction of D+ -> K* (892)(+)pi(0) is determined to be (4.4(-1.5stat)(+1.8) +/- 0.2(syst)) x 10(-4), with a statistical significance of 3.2 sigma. No significant signal for D+ -> K* (892)(+)pi(0) is found and we set an upper limit on the branching fraction of this decay at the 90% confidence level to be 5.4 x 10(-4).en_US
