Abstract
We report measurements of branching fractions for charged and neutral B-->eta(c)K decays where the eta(c) meson is reconstructed in the K(S)(0)K(+/-)pi(-/+), K(+)K(-)pi(0), K(*0)K(-)pi(+), and p (p) over bar decay channels. The neutral B-0 channel is a CP eigenstate and can be used to measure the CP violation parameter sin2phi(1). We also report the first observation of the B-0-->eta(c)K(*0) mode. The results are based on an analysis of 29.1 fb(-1) of data collected by the Belle detector at KEKB.
