New result on phase shift analysis
André Martin, Jean-Marc Richard
Assuming a certain continuity property, we prove, using the old results of Itzykson and Martin, that, except for an obvious ambiguity, there are only at most two amplitudes reprodu…
A rigorous lower bound on the scattering amplitude at large angle
Henri Epstein, André Martin
We prove a lower bound for the modulus of the amplitude for a two-body process at large scattering angle. This is based on the interplay of the analyticity of the amplitude and the…
A Lower Bound on Inelasticity in Pion-Pion Scattering
André Martin, S. M. Roy
Assuming that the pion-pion scattering amplitude and its absorptive part are analytic inside an ellipse in - plane with foci , and right extremity , ($ε…
Positivity of the real part of the forward scattering amplitude
André Martin, Tai Tsun Wu
We prove the general theorem that the real part of the forward two-body scattering amplitude is positive at sufficiently high energies if, above a certain energy, the total cross s…
An upper bound on the total inelastic cross-section as a function of the total cross-section
Tai Tsun Wu, André Martin, Shasanka Mohan Roy +1
Recently André Martin has proved a rigorous upper bound on the inelastic cross-section at high energy which is one-fourth of the known Froissart-Martin-Lukaszuk upper bo…
The Froissart bound for inelastic cross-sections
André Martin
We prove that while the total cross{}-section is bounded by , where is the square of the c.m. energy and the mass of the pion, the total inelastic cros…
