Resumo: We study the Borel sum rule for the tensor amplitude of the processes J/y p ® D*, D, *D* and D*. We also evaluate the cross sections as a function. We find that our results are smaller than the J/y p ® charmed mesons cross sections obtained with models based on meson exchange, but are close to those obtained with quark exchange models.
