How imposing analyticity on a $\pi\pi$ phase shift analysis can reveal new solutions, explore experimental structures, and investigate the possibility of new resonances
Experiments on pi pi scattering determine only the modulus of the amplitude in the inelastic region. Fixed t and u analyticity in the form of conventional dispersion relations are used to determine the phase of the amplitude in this region. This analysis allows local structures in data to be isolate...
