摘要：

We set up a general framework to describe pi pi scattering below 1 GeV based on chiral low-energy expansion with possible spin-0 and -1 resonances. Partial wave amplitudes are obtained with the N/D method, which satisfy unitarity, analyticity, and approximate crossing symmetry. A comparison with the phase shift data in the J = 0 channel favors a scalar resonance near the rho mass. [80556-2821(99)00901-7].
