Abstract: We extend the Vecchia–Veneziano–Witten model of quantum chromodynamics in the chiral limit and for large colour number N c , by introducing an effective dilaton–gluon coupling from which we derive both the axion and dilaton potentials. Furthermore, using a string-inspired model, we determine a new interquark potential as a perturbative series in terms of the interquark distance r . Our potential goes beyond Dick's potential (Dick R 1999 Eur . Phys . J . C 6 701) and shares the same features as those of the Bian–Huang–Shen potential ( V BHS ) which depends only on odd powers of r (Bian J G, Huang T and Shen Q X 1994 Commun . Theor . Phys . 21 333).
