PROTON-ANTIPROTON SCATTERING AND QUARK-DIQUARK STRUCTURE

An unsymmetrized nucleon wave function obtained by adding the possible quark-diquark structure to the usual spatially symmetric wave functio n is used to calculate the elastic proton-antiproton multiple scatteri ng amplitudes. Numerical computation is made on the double scattering term. Results show that the amplitude from the unsymmetrized wave func tion is larger in absolute magnitude than that from the symmetric one. The difference becomes more visible as the momentum transfer increase s. This feature is briefly discussed.
