Intermediate inelastic states inpdscattering and the triple-Regge couplings

Abstract

The high-energy real and imaginary parts of the pd forward amplitude are compared with those predicted by the Glauber theory. The differences are qualitatively explained including the intermediate inelastic states in the framework of the triple-Regge formalism. A Pomeron with intercept larger than one is clearly required. In a quantitative way the RRR and RRP couplings extracted from inclusive data cannot explain the difference of the real parts. We study the possibility of changing the values of these couplings in order to explain such a difference without spoiling the fit to inclusive data.

The deuteron in high-energy physics

“…Amplitudes for such processes can be estimated within Regge theory (Gribov, 1969;Kancheli and Matinyan, 1970;Anisovich, Volkovitsky and Dakhno, 1972;Quigg and Wang, 1973;Kwiecinski, Lesniak and Zalewski, 1974;Baig and Pajares, 1979).…”
