AbstractAbstract
[en] Theoretical interpretations of several new experimental results on low-energy p-barp interactions are presented. An effective range analysis of the LEAR data on p-barp elastic scattering and p-barp→n-barn charge-exchange reaction is carried out. Tentative reasons for the unusual behaviour of the real-to-imaginary ratio of the p-barp forward elastic scattering amplitude are pointed out. Restrictions on the NN-bar amplitude imposed by the strong interaction shift and width of the 1S-state of the antiprotonic hydrogen are derived. Evidence for the appearance of the Barry topological phase in antiprotonic hydrogen is presented. 50 refs.; 3 figs
