The linear U3 x U3 sigma Model, the sigma resonance and the spontaneous breaking of symmetries
Nils A. Tornqvist (University of Helsinki)🇫🇮
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.
