The linear U3 x U3 sigma Model, the sigma resonance and the spontaneous breaking of symmetries
arXiv:hep-ph/9711483 · doi:10.1063/1.55987
Abstract
My recent fit of the light scalar mesons is discussed in the light of the U3 x U3 linear sigma model. The argument for why there exists a light and broad sigma meson is explained in more detail, and the mechanism of spontaneous symmetry breaking is discussed.
