Structure of scalar mesons Higgs sector strong interaction
2011/7/21
The scalar mesons $\sigma(600)$, $\kappa(800)$, $f_0(980)$ and $a_0(980)$ together with the pseudo Goldstone bosons $\pi$, $K$, and $\eta$ may be considered as the Higgs sector of strong interaction.
Scalar field in nuclear matter: the roles of spontaneous chiral symmetry breaking and nucleon structure

Chiral theories with spontaneous symmetry breaking such as the Nambu-Jona-Lasinio (NJL)
model lead to the existence of a scalar mode. We present in a detailed manner how the corresponding low momentu...
