| Abstract: | Flavour symmetry breaking is introduced in the approximate formula for quark mass reported earlier. We use SLAC-MIT as well
as NMC data to estimate the up, down and strange quark masses from structure functions. Using the approximateQ
2 evolutions of Altarelli-Parisi equations, we also estimate its perturbative and nonperturbative components. |
