The applicability of perturbative QCD to the pion form factor and the pionic wavefunction
Description
We reanalyse the pionic form factor by using perturbative QCD theory and contributions from endpoint regions. We find that the perturbative QCD can be applied to the pionic form factor as Q2>4 GeV2 and they become unreliable as Q2≤4 GeV2. Therefore the applicability of perturbative QCD to the form factor is questionable only as Q2≤4 GeV2. (orig.)
