Abstract
Generalizing a recent convolution model of the nucleon which explicitly conserves charge and momentum we reexamine the influence of an enhanced pion field in nuclei on EMC and Drell-Yan ratios. Due to wave function renormalization constants the effect is more than 50% smaller than predicted by the standard pion excess model. In particular there is no discrepancy between the EMC data and our results in the x-region which was expected to be most sensitive to the pion.
