Abstract

We present the results of a Dalitz plot analysis of D-0 -> K-S(0)pi(0)pi(0) using the CLEO-c data set of 818 pb(-1) of e(+)e(-) collisions accumulated at root s = 3.77 GeV. This corresponds to 3 x 10(6) D-0(D) over bar (0) pairs from which we select 1259 tagged candidates with a background of 7: 5 +/- 0: 9 percent. Several models have been explored, all of which include the K*(892), K-2*(1430), K*(1680), the f(0)(980), and the sigma(500). We find that the combined pi(0)pi(0) S-wave contribution to our preferred fit is (28.9 +/- 6.3 +/- 3.1)% of the total decay rate while D-0 -> (K) over bar*(892)(0)pi(0) contributes (65.6 +/- 5.3 +/- 2.5)%. Using three tag modes and correcting for quantum correlations we measure the D-0 -> K-S(0)pi(0)pi(0) branching fraction to be (1.058 +/- 0.038 +/- 0.073)%.

We find that the combined pi(0)pi(0) S-wave contribution to our preferred fit is (28.9 +/- 6.3 +/- 3.1)% of the total decay rate while D-0 -> (K) over bar*(892)(0)pi(0) contributes (65.6 +/- 5.3 +/- 2.5)%. Using three tag modes and correcting for quantum correlations we measure the D-0 -> K-S(0)pi(0)pi(0) branching fraction to be (1.058 +/- 0.038 +/- 0.073)%.
