Abstract

摘要

In this talk, I analyze vector meson - vector meson scattering in a unitarized chiral theory based on a chiral covariant framework. I show that a pole assigned to the the scalar meson f0(1370) can be dynamically generated from the rho-rho interaction, while this is not the case for the tensor meson f2(1270) as found in earlier works. The generation of the tensor state is untenable due to an artifact of the extreme non-relativistic kinematics used in the literature in a number of works. Effects arising from the coupling of channels with different orbital angular momenta is also considered. I suggest to use the formalism outlined here to obtain more reliable results for the dynamical generation of resonances in the vector-vector interaction.
