Higgs boson and meson: Is there a mystery of mass?[edit]

The generation of mass of particles is generally attributed to the interaction of the originally massless particle with the Higgs field. This Higgs field is a property of the electroweak (EW) vacuum with a spontaneously broken symmetry. The particle corresponding to the Higgs field is named Higgs boson. There are strong indications that a Higgs boson with a mass of 125 GeV has been found in the ATLAS and CMS experiments at CERN. However, according to present knowledge only 2% of the ordinary matter may be attributed to the Higgs boson. These 2% show up in the form of current-quark masses amounting to MeV for the up quark and MeV for the down quark. The other 98% of the mass are due to the QCD vacuum which contains quark-antiquark pairs and gluons. This dominant contribution to the mass of the nucleon is mediated through the exchange of a meson between the constituent quarks inside the nucleon and the pairs of the QCD vacuum. This consideration leads to the conclusion that a meson with a mass of MeV should be part of the structure of the constituent quarks of the nucleon. The question arises whether or not it is possible to detect this meson while being part of the mesonic structure of the constituent quark. As has been recently shown this is indeed posiible and actually has been carried out in a Compton scattering experiment by the nucleon [1]. The meson is capable to simultaneously couple to two photons and, therefore, may serve as an intermediate state in a Compton scattering experiment by the nucleon. The following observations have been made: (i) The presence of the meson on the constituent quarks has a large effect on the differential cross section for Compton scattering and leads to a determination of the mass with the result MeV. (ii) Due to the spin structure the nucleon is expected to be paramagnetic which is not observed experimentally. The explanation is provided by the meson which is a source of a diamagnetic polarizability. Conclusion: The meson may be considered as the Higgs boson of strong interaction because it generates the missing 98% of the mass of the nucleon through interaction with the QCD vacuum. The meson as part of the constitient quark structure has been observed in a Compton scattering experiment by the nucleon [1]. The explains the strong diamagnetic polarizability of the nucleon.
