The approach given in our paper hep-ph/9811318, "On a possible estimation of the constituent--quark parameters from Jefferson Lab experiments on the pion form factor" makes it possible to estimate the mass of constituent quark from such kind of experiment. Now this estimation gives M=0.21 GeV.2 pagesNuclear TheoryHigh Energy Physics - PhenomenologyNuclear Experimenttext
