Molecular Interpretation of the Supercharmonium State Z(4475)

Abstract

Charm meson molecule (c\bar n)(n\bar c) assignments for the supercharmonium state Z(4475) are considered, both on general grounds and in the context of specific pion exchange models. Two possible charm molecule assignments for the JP = 1+, 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 D \bar D plus n pions is recommended as a test of the nature of these states.
