Dalitz Plot Analysis of Three-body Charmonium Decays at BABAR

摘要

We present results on the measurement of the I=? Kπ S -wave through a model independent partial wave analysis of η_(c) decays to K~(0)_(s)K~(+)π~(?) and K~(+)K~(?)π~(0) produced in two-photon interactions. We also perform Dalitz plot analyses of the J/Ψ decays to π~(+)π~(?)π~(0) , K~(+)K~(?)π~(0) and K~(0)_(s)K~(±)π~(?) produced in the initial state radiation process.
