Abstract

We prove that the Fourier transform of the exponential e- V(R) of the static interquark potential in QCD is positive. It has been shown by Eliott Lieb some time ago that this property allows in the same limit of static spin independent potential proving certain mass relation between baryons with different quark flavors.
