Models for High-Energy Processes

High-Energy Hadron--Deuteron Scattering.

“…For the connection between multiple scattering and Regge cuts see the discussion-by Jackson (1970). The case against imputed structure is developed at more length by Quigg (1970) ·' but for an opposing view, the rejection of exchange degeneracy, see Risk (1970).]…”

Two Reggeon exchange contributions to hadron scattering amplitudes at high energy

“…This is one of the ideas I wish to elucidate here. Already in Chapter IV I gave a rather formal statement of what exchange degeneracy means, to wit p (s,t) = 0. su An explanation of the connection between the absence of exchange forces and exchange degeneracy may be found in Section V-3(b) of Jackson (1970), or in Arnold (1965).…”

“…For small values of a( s), the logarithm varies rapidly, and the net ene:r.·gy dependence will resemble that characterized by a power somewhat lower than acut· (For a more explicit demonstration, see Fig. 18 of Jackson, 1970. …”

“…Further references for photoproduction may be found in Quigg (1969., 1970). An enligh~ening discussion of the behavior at t = 0 is given in Appendix B(e) of Jackson (1970).…”

“…I hasten to add that the difficulties with Regge poles are quantitative and in no way minimize the remarkable fecundity of the Regge pole hypothesis (Regge, 1959(Regge, , 1960Frautschi, 1961, 1962), which is exposited by Barger and Cline (1969). The case for Regge cuts has.been reviewed by Chiu (1969), Fox (1970), Jackson (1970), and Sonderegger (1969).…”
