Abstract

The radiative transitions from the neutral exotic Zc(4020)0 resonance to X(3872) with emission of a photon and the pionic transitions from the charged Zc(4020)± to X(3872) and a charged pion π± are considered for both charmoniumlike states being charmed meson-antimeson molecules. The underlying processes for these transitions are the decays of the charmed vector meson to pseudoscalar plus a photon or a pion. It is found that the discussed transition rates typically amount to a branching fraction of several permil with a peak at the vector meson pair threshold.
