摘　　要：Based on the eikonalized Glauber representation of hadron-hadron scattering, we study the diffractive processes of ^-pp and pp elastic scattering at high energies. From our theoretical calculations and fits to the corresponding experimental data at high energies and all available momentum transfer, we find that the Pomeron exchange contributions play a significant role in description of differential cross section dσ/dt in the whole experimental domain. The Pomeron exchange contributions are related to multi-gluon exchanges in QCD, which are color singlet bound state of Reggeized gluons, such as tensor glueball and Odderon. Accordingly, we may claim that the ^-pp and pp diffractive processes at high energies s and moderate momentum transfer t would be a good tool to verify the existence of the color singlet multigluon bound states and to test QCD since QCD theory does predict the existence of these states. Therefore, we believe that the experimental measurement should be done for these diffractive processes.
