Common explanation of the behavior of some e+e- annihilation processes around sqrt s =1.9 GeV
Original language description
We show that the behavior of the excitation curves of some e+ e- annihilation processes close to the nucleon-antinucleon threshold can be explained either by the rho(1900) resonance itself or by its interference with other resonances. Besides the six-pion annihilation and the e+ e- -> K+ K- pi +pi- and Phi pi0 processes, we also analyze the final states eta pi+ pi-, K+ K- pi+ pi- pi0, and K+ K- pi0 pi0, the behavior of which around 1.9 GeV has not yet attracted attention. Analysis of the data on the e+ e- -> p p and e+ e- -> n n reactions clearly shows that the rho(1900) resides above the n n threshold.
