Dressed quarks in <strong>the</strong> Nucleon<br />
Dressed quarks are a consequence <strong>of</strong> dynamical chiral symmetry<br />
breaking (DCSB) in QCD.<br />
Dressed quarks and antiquarks constituents are described/predicted by<br />
Dyson-Schwinger Equations (DSEs). <strong>The</strong> quarks-partons <strong>of</strong> QCD acquire<br />
a momentum dependent mass that in <strong>the</strong> infra-red limit is 2 orders <strong>of</strong><br />
magnitudes larger than <strong>the</strong> current-quark mass; mostly due to a cloud<br />
<strong>of</strong> gluons surrounding a low-momentum quark.<br />
In this approach <strong>the</strong> Higgs boson does not contribute to <strong>the</strong> mass<br />
<strong>of</strong> <strong>the</strong> visible universe!<br />
