Constraints imposed by the data above 1 GeV on the low energy $\pi\pi$ amplitudes
The authors study the influence of the region above 1 GeV on low- energy pi pi amplitudes by using minimum subtracted dispersion relations, in addition to the twice subtracted ones. When the results are compared with the recent phase-shift analysis below 1 GeV, they find that the S-wave isospin-zero...
