# Linear rising potential from a Gribov propagator

It is common wisdom that a gluon propagator (Gribov-)like $$G(p^2)=\frac{a+bp^2}{cp^4+dp^2+e}$$ should give rise to a linear rising potential. So far, I have not seen a proof of this and I would like to get a mathematical derivation, or a reference, displaying how a potential emerges from it.

Thanks.
