英文摘要: Bottomed on isospin-SU(2) invariant coupling model which describes the strong interaction between pion and nucleon-antinucleon, for the first time the differential cross-section (DCS) of neutron-neutron scattering with renormalized infinite high-order hybrid loop-chain propagators is "strictly" calculated. DCSs between cases of the hybrid loop-chain propagator (HLCP) and the tree propagator are compared, and it shows that the radiative corrections we obtained are mainly less than 0.9 in typical range of parameters. These results may indicate that the utilization of HLCP underlying the effective way towards the enhanced precision would be considerable. The outcomes might contribute to studies on the nucleon collisions and also possible issues of some phenomena in particle astrophysics.
