For this purpose we extract the charm vacuum polarisation via a standard dispersion relation from BESII-data on $e^+e^-\\to hadrons$. In the factorisation approximation (FA) the vacuum polarisation describes the interference fully non-perturbatively. The observed interference pattern by the LHCb collaboration is opposite in sign and and significantly enhanced as compared to the FA.
