摘要:In this work we present our model that dynamically generates resonances from charmed and
light pseudoscalar and vector mesons. The model generates a rich spectrum of charmed and
hidden charm scalar and axial resonances, most of them which can be associated with observed
states. Other states are predicted, in particular a hidden charm scalar resonance with mass close
to the D¯D threshold. For this resonance we present calculations which show that an observed
enhancement in the D¯D mass spectrum measured by Belle in reactions producing D¯DJ/y in the
final state could be originated by this predicted state. We also present theoretical calculations on
the radiative decay width of they(3770) into this state. The predicted branching fractions suggest
that this predicted state could be observed by BES with statistics of one year run in the y(3770)
peak.
