Abstract

It is argued that the charged Zc+(3885) resonance, treated as a "molecular" state of charmed D and D∗ mesons, is likely to consist of two peaks unequally coupled to the D∗+D0 and D+D∗0 channels. The peaks should be split in mass by at least approximately 1.5 MeV. This behavior arises from an enhancement of the effect of isospin violation in the masses of the D and D∗ mesons due to apparent suppression of forces between the mesons depending on the spins of the heavy as well as the light quarks. The suggested double-peak structure can be studied either by direct shape measurement in the channels with heavy mesons, or by isospin-violating transitions from Zc±(3885) to the states of charmonium plus a light meson.
