Description
It has been discussed for a long time that light flavors, i.e., up, down and strangeness, give a variety of exotic hadrons. One of the most important examples are scalar mesons and glueballs. In this talk, we discuss these better-known light exotic particles from new perspectives. Firstly, we discuss a new framework for inner-structures of scalar mesons, and propose to study them by experiments in relativistic heavy ion collisions. Secondly, we present the Hopfion picture for glueball candidates in scalar mesons, and discuss their mass spectra in terms of the Skyrme-Faddeev model. Those studies will serve a new point of view for immemorial exotic hadrons.
