Intermediate inelastic states in pd scattering and the triple-Regge couplings

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. © 1979 The American Physical Society.
