title: On some positivity properties of the interquark potential in QCD.
abstract: We argue that the Fourier transform of the exponential e(-betaV(R)) of the static interquark potential in QCD is positive. It has been shown by Lieb some time ago that this property allows in the same limit of static, spin independent potential, to prove a certain mass relation between baryons with different quark flavors.
