    "abstract": "The quark Dyson-Schwinger equation shows that there are distinct differences\nbetween light and heavy quarks. The dynamical mass function of the light quarks\nis characterised by a sharp increase below 1 GeV, whereas the mass function of\nthe heavy quarks is approximately constant in this infrared region. As a\nconsequence, the heavy-meson masses increase linearly with the current-quark\nmasses, whereas the light pseudoscalar meson masses are proportional to the\nsquare root of the current-quark masses.",
