We show that scalar Feynman integrals are Stieltjes functions in each kinematic variable and each internal mass separately, for arbitrary loop order and number of legs, whenever a simple condition on the propagator exponents holds. The proof rests on a decomposition of the second Symanzik polynomial into manifestly non-negative terms indexed by spanning two-forests. The property has direct...
