Abstract

We describe meson wave function by a QCD euclidean four-point function. We prove that this function is maximal at the origin and then get the stronger result that it has a positive Fourier transform. We also discuss the monotonicity of the function, which might probe more specific features of QCD, than just positivity of the integration measure over the gauge configurations.
