It is shown that the Quark-Level Linear σ Model (QLLσM) leads to a prediction for the diamagnetic term of the polarizabilities of the nucleon which is in excellent agreement with experimental data. The bare mass of the σ meson is predicted to be m
σ
=666 MeV and the two-photon width Γ(σ→γ
γ)=(2.6±0.3) keV. It is argued that the mass predicted by the QLLσM corresponds to the 
reaction, i.e. to a t-channel pole of the γ
N→N
γ reaction. Large-angle Compton scattering experiments revealing effects of the σ meson in the differential cross section are discussed. Arguments are presented that these findings may be understood as an observation of the Higgs boson of the strong interaction while being a part of the constituent quark.
