Abstract

We study the processes c 0 K K -, 0 -, and -using a data sample of 519 fb -1 recorded with the BABAR detector operating at the SLAC PEP-II asymmetric-energy e e -collider at center-of-mass energies at and near the nS (n 2, 3, 4) resonances. This is the first observation of the decay c 0 K K -and we measure the branching fraction
