Mass generation via the Higgs boson and the quark condensate of the QCD vacuum

TL;DR

This paper derives hadron masses from the quark condensate of the QCD vacuum and the Higgs boson, extending previous work to include strange quarks and predicting properties of scalar mesons and hyperons.

Contribution

It introduces a method to calculate hadron masses using the QCD vacuum structure and Higgs interactions, including strange-quark effects and meson predictions.

Findings

Hadron masses derived from quark condensate and Higgs effects.

Predicted the second sigma meson as f0(1370).

Extended analysis to hyperons like Lambda and Sigma.

Abstract

The Higgs boson, recently discovered with a mass of 125.09$\pm$0.24 GeV is known to mediate the masses of elementary particles, but only 2% of the mass of the nucleon. Extending a previous investigation [1] and including the strange-quark sector, hadron masses are derived from the quark condensate of the QCD vacuum and from the effects of the Higgs boson. These calculations include the $\pi$ meson, the nucleon and the scalar mesons $\sigma(600)$, $\kappa(800)$, $a_0(980)$ $f_0(980)$ and $f_0(1370)$. The predicted second $\sigma$ meson $\sigma'(1344)=|s\bar{s}\rangle$, is investigated and identified with the $f_0(1370)$ meson. An outlook is given on the hyperons $\Lambda$, $\Sigma^{0,\pm}$ and $\Xi^{0,-}$.
