Resumen:
|
We review the N_c and m_? dependence of the rho(770) and ? (or f_0(600) resonances generated with the Inverse Amplitude Method. The ? N_c behavior is at odds with being dominantly a q?q? state, but there is a hint of a subdominant q?q?o component with a mass above 1 GeV. We find fair agreement with lattice results for the chiral extrapolation of the ? mass, and that the ? ? ? coupling is almost m_? independent whereas the ? ? ? depends strongly on m_?.
