摘要: The charge radius of the pion and charged neutral kaon is calculated in a coloured quark field theory at one loop level. only free parameter mass ratio. Both theoretical arguments experimental data favour interpretation these masses as constitutent not current ones. obtained description good. We conclude with some remarks about quantitative significance calculations.
