Abstract: (APS)

We prove the general theorem that the real part of the crossing even forward two-body scattering amplitude is positive at sufficiently high energies if, above a certain energy, the total cross section increases monotonically to infinity at infinite energy.

In these papers, there is a small confusion: the authors say that E is the so called "laboratory energy" of one particle, but if masses are different, it is not. It is in fact proportional to our variable ξ
