Abstract:
Within the framework of the Glauber theory, we divide the many particle systeminto two subsystems formed. by the "valence" particles and "sea" particles respective-ly. Then the multiple scattering amplitudes can be divided into "sea","sea","sea","valence", "valence","sea", and "valence","valence" multiple scattering amplitude.For the calculations of these different amplitudes different effective approximatemethods are proposed, Finally, for "sea"."sea". "sea""valence", "valence" "sea"and "valence"."valence" processes, we obatain the respective S-matrices which phy-sically clear and convenient in calculation.
