Charge Sum Rules for Quark Fragmentation Functions / D.Kotlorz, O.Teryaev. – Text : electronic // Physical Review C. – 2025. – Vol. 112, No. 3. – P. 035204. – URL: https://doi.org/10.1103/5q6n-9ll7. – Bibliogr.: 23.

Charge sum rules for quark fragmentation functions are studied. The simultaneous implementation of the conservation of electric and baryon charges, strangeness, and isospin symmetry is achieved when the fragmentation to both mesons and baryons is considered. The results are compatible to Gell-Mann–Nishijima formulas and may be the new manifestation of superconformal symmetry between mesons and baryons. The numerical estimates are performed and compared with phenomenological models. The recently suggested violations of sum rules due to Wilson line contributions are discussed.
