On the mass shell
Webbe the mass shells (cones) corresponding to mass m > 0 (m = 0) and let H+ im = fp 2R4: p2 = m2, p0 > 0g, (4) and H im = fp 2R4: p2 = m2, p0 < 0g, (5) be the positive time … Webapplications to scattering theory. As a matter of fact, no explicit expression for the perturbed mass shell is provided in [Can71]. Finally, for the massless Nelson model, the result concerning the existence of the mass shell was extended by Fro¨hlich to arbitrarily small infrared cut-off with no restriction on the coupling constant.
