Since the number of relevant partial waves grows with energy, additional theoretical constraints are necessary to constrain the amplitudes. Dispersive approaches allow one to use high-energy data to constrain the low-energy models that aim at mapping the baryon spectrum. I illustrate how the dispersive approach of Finite-Energy Sum Rules can be used to do the inverse: predicting the scattering amplitudes at high energies based on low-energy models.</div><br></div>_______________________________________________<br>Theory-seminars mailing list<br><a href="mailto:Theory-seminars@jlab.org">Theory-seminars@jlab.org</a><br>https://mailman.jlab.org/mailman/listinfo/theory-seminars<br></div></blockquote></div><br></body></html>
