Abstract
From a study of the X(3872) mass and width based on the world's largest sample of decays, we find that our X(3872) signal is consistent with a single state, and leads to the most precise measurement of the X(3872) mass. We also report the recent evidence for a new narrow structure, Y(4140), decaying to the final state, in exclusive decays in a data sample corresponding to an integrated luminosity of 2.7 \ifb collected at the CDF II detector. This narrow structure with its mass well above open charm pairs is unlikely to be a candidate for a conventional charmonium state.
