摘要：

The Bjorken-Johnson-Low theorem applied to the gamma* --> gamma*pi(0) process provides us with a rather remarkable asymptotic behaviour for the pi(0) gamma*gamma* vertex. We compare our result with previous QCD- inspired estimates and argue that the predicted behaviour is quite consistent with the present data on hadronic J/Psi decays and ensures the matching of long- and short-distance radiative corrections to pi(+) --> e(+)v(e).
