- By analyzing an electron-positron collision data sample corresponding to an integrated luminosity of 2.93 fb(-1) taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, we obtain for the first time the absolute branching fractions for seven D-0 and D+ hadronic decay modes and search for the hadronic decay D-0 ->(KSKS0)-K-0 pi(0) with much improved sensitivity. The results are B(D-0 -> KS0 pi 0 pi 0 pi 0)=(7.64 +/- 0.30 +/- 0.29)x10(-3), B(D-0 -> K-pi(+)pi(0)pi(0)pi(0))=(9.54 +/- 0.30 +/- 0.31)x10(-3), B(D-0 -> KS0 pi+pi-pi 0 pi 0)=(12.66 +/- 0.45 +/- 0.43)x10(-3), B(D+-> K-S(0)pi+pi(0)pi(0))=(29.04 +/- 0.62 +/- 0.87)x10(-3), B(D+-> K-S(0)pi+pi+pi-pi(0))=(15.28 +/- 0.57 +/- 0.60)x10(-3), B(D+-> K-S(0)pi+pi(0)pi(0)pi(0))=(5.54 +/- 0.44 +/- 0.32)x10(-3), B(D+-> K-pi+pi+pi(0)pi(0))=(4.95 +/- 0.26 +/- 0.19)x10(-3), and B(D-0 ->(KSKS0)-K-0 pi(0))<1.45x10-4 at the 90% confidence level. Here, the first uncertainties are statistical, and the second ones are systematic. The newly studied decays greatly enrich the knowledge of the D -> <(K)over bar>pi pi pi and D -> (K) over bar pi pi pi pi hadronic decays and open a bridge to access more two-body hadronic D decays containing scalar, vector, axial, and tensor mesons in the charm sector.
