Generalized superconvergence relations for KN and scattering are used to deduce parameters of the rho meson trajectory. Results are found to be in reasonable agreement with those from previous analyses using different by: 1. the decouplet exchange superconvergence relations for meson-baryon scattering and cuts in the complex j-plane.

Assuming Regge trajectories fall linearly for negative t, we formulate superconvergence relations at infinetely many discrete t values. We saturate with an infinite number of resonances: but only a finite number is involved at each finite ng the spacing in the grid Δs = Δt = (α′) −1 we construct a solution, which turns out to be the Veneziano formula.

For pion Compton scattering therefore, this behaviour will be s a-2 according to (14). Finally, we remark on the matrix structure of the crossing relations for massless particles. Since it is a c-number it must be taken as b.A',for a particle which is in(out)going in both channels. relations for hadron-hadron scattering. The proof is given for pi-pi scattering; but the extension to pi-N scattering is straightforward if the gap method is also used for the pi-N vertex. PROOF OF DISPERSION RELATIONS AND THE EDGE OF THE WEDGE THEOREM Reinhard Oehme Colloquium presented at Palmer Hall, Princeton University, Winter /57;.   By expressing the free theory on the light-front, we show that flavor doubling implies several superconvergence relations in pion-hadron scattering. Implicit in the 2N-flavor effective theory is a Regge trajectory with vacuum quantum numbers and unit intercept whose behavior is . Books at Amazon.

It is shown that, if the superconvergence relations appertaining to a two‐particle scattering process are saturated by an infinite tower of resonances of mass mJ, where J is the spin, then mJ must increase less quickly than J in all cases. With this observation, it is shown that the complex of all the superconvergence relations for all the processes a(J1) + a(J2) → a(J3) + a(J4), where a(J. In the spring of I stayed at the ICTP in Trieste for five months. Towards the end of the stay K. C. Wali and I traveled to Israel, specifically the Weizmann Institute for ten days at the invitation of H. J. Lipkin. When we arrived in Israel we found that the atmosphere was extremely tense and people busy preparing for a war with the neighboring Arabic countries. Although the touristy. A brief discussion of isospin is followed by treatment of low energy pion scattering, dispersion relations, scattering amplitudes, nucleon resonances, symmetries, current algebra and sum rules. Reinhard Oehme (German: ; born 26 January , Wiesbaden; died sometime between 29 September and 4 October , Hyde Park) was a German-American physicist known for the discovery of C (charge conjugation) non-conservation in the presence of P violation, the formulation and proof of hadron dispersion relations, the "Edge of the Wedge Theorem" in the function theory of several complex.
