| Research Abstract |
Strong interaction is governed by quantum chromodynamics. At low energy, due to the nonperturbative dynamics, hadrons emerge as the physical degrees of freedom. In this study, based on the chiral effective theory with hadronic degrees of freedom, we investigate the structure of exotic hadrons as well as the methods to verify the structures in experiments. It is shown that the hadronic molecular structure of the Lambda(1405) resonance and the sigma meson can be clarified by observing the particle yields in the heavy ion collisions and the modification of the spectrum along with the partial symmetry restoration.
