Description
We have demonstrated that the charge sum rules for the quark fragmentation functions hold including simultaneously the contributions of mesons and baryons providing the conservation of the strangeness, electric and baryon charges. We also obtained the expression for the isospin conservation. The results are compatible to Gell-Mann–Nishijima formulas for quarks and hadrons manifesting a new aspect of quark-hadron duality.
Using our results, we formulated the constraints for the quark fragmentation functions to mesons π, K and baryons p, n, Λ. The numerical estimates based on some recent parametrizations of FFs confirm these constraints and also are in agreement with the truncated contributions to the charge and isospin sum rules.
