Abstract
Charm meson molecule assignments for the supercharmonium state1 Z(4475) are considered, both on general grounds and in the context of specific pion-exchange models. Two possible charm molecule assignments for the Z(4475) are considered here, involving respectively a radially and an orbitally excited charm meson. In each assignment, a lower-mass isosinglet charm molecule state is predicted. For both the Z(4475) and the Y(4260), measurement of the ratios of the branching fractions to plus pions is recommended as a test of the nature of these states.
