Conference Report: Structure of scalar mesons and the Higgs sector of strong interaction

Abstract

The $\sigma$ mesons may be considered as the Higgs boson of strong interaction. While the observation of the electroweak Higgs boson is the primary goal in ongoing experiments at the LHC, the $\sigma$ meson is by now well studied both as an on-shell particle and as a virtual particle while being part of the constituent quark. This makes it timely to give an overview of the present status of the Higgs sector of strong interaction which includes the scalar mesons $\sigma (600)$, $\kappa (800)$, $f_0(980)$ and $a_0(980)$ together with the pseudo Goldstone bosons $\pi$, $K$ and $\eta$.
