Abstract: | Using recent data on pion structure function and a rigorous inequality obtained recently using unitarity analyticity and Bjorken
scaling a numerical upper bound on the wave-function-renormalisation constant of pion is computed. By the (somewhat drastic)
act of neglecting the sea, it is shown that the bare part of the pion can be no more than 38%. |
