Multichannel analysis of low-energy\(N\bar N\) interactionsinteractions

The multichannelM-matrix method is applied to a nucleon-antinucleon system by taking into account elastic proton-antiproton scattering, charge exchange reaction and annihilation. Thes, p andd-waves are considered with the effective-range approach to describe the differential and total cross-sections for elastic proton-antiproton scattering and charge-exchange scattering, total cross-sections and real-to-imaginary ratio of the forward amplitude of elastic scattering. Thep-wave bound state which leads to high anisotropy of\(\bar pp\) reactions was found.
