Abstract
We present the results of a Dalitz plot analysis of D0 > KS(0)pi(0)pi(0) using the CLEOc data set of 818 pb(1) of e(+)e() collisions accumulated at root s = 3.77 GeV. This corresponds to 3 x 10(6) D0(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), K2*(1430), K*(1680), the f(0)(980), and the sigma(500). We find that the combined pi(0)pi(0) Swave contribution to our preferred fit is (28.9 +/ 6.3 +/ 3.1)% of the total decay rate while D0 > (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 D0 > KS(0)pi(0)pi(0) branching fraction to be (1.058 +/ 0.038 +/ 0.073)%.
