Abstract
Using 6.32 fb(-1) of e(+)e(-) collision data collected by the BESIII detector at the center-of-mass energies between 4.178 and 4.226 GeV, an amplitude analysis of the D-s(+) -> (KSK-)-K-0 pi(+)pi(+) decays is performed for the first time to determine the intermediate-resonant contributions. The dominant component is the D-s(+) -> K*(892)(+)(K) over bar*(892)(0) decay with a fraction of (40.6 +/- 2.9(stat) +/- 4.9(sys))%. Our results of the amplitude analysis are used to obtain a more precise measurement of the branching fraction of the D-s(+) -> (KSK-)-K-0 pi(+)pi(+) decay, which is determined to be (1.46 +/- 0.05(stat) +/- 0.05(sys))%.
