Models for meson-deuteron scattering in the resonant region

"The Watson formulation of multiple scattering theory is derived and then employed to build a model for meson-deuteron scattering. The Glauber theory is also derived as an approximate form of multiple scattering theory. The developed model extends the Glauber description to regions in which the mesonnucleon cross section varies rapidly or' resonates, by including effects caused by the nucleons' Fe-rmi momenta, non-forward intermediate scattering, and off-energy shell scattering. It is concluded, after a numerical analysis, that Glauber theory itself could generate the large oscillations in <r-2>d reported in the analysis of 7T+d total cross sections around 1 GeV / c and could introduce small peaks into the deduced 1=0 channel of the k+n cross section. Nevertheless, for the k+d data of Cool et ale conclusions drawn by following the usual folding procedures are not altered significantly by this model. The importance of different possible definitions of center-of-mass energy for off-shell scattering is also examined. It is shown that this choice of ""s"" does not affect total cross section calculations, but must be considered in the analysis of large angle scattering."
