A flavor dependent kernel is constructed based on the rainbow-ladder truncation of the Dyson-Schwinger and Bethe-Salpeter equations in quantum chromodynamics.The quark-antiquark interaction is composed of a flavor dependent infrared part and a flavor independent ultraviolet part.Our model gives a successful and unified description of the light,heavy and heavy-light ground state pseudoscalar and vector mesons.Our model shows,for the first time,that the infrared enhanced quark-antiquark interaction is stronger and wider for lighter quarks.
