The present book covers the complete formulation of the Standard Model of the Theory of Fields. The full theory comprehends the leap from relativistic theories up to the Higgs hunt. The text includes the discussion of second quantization, Feynman rules, and QED radiative corrections. Weak forces and the Electro-Weak Symmetry Breaking (EWSB) are then broached. QCD is eventually introduced with emphasis on the connection between QED and QCD provided by the Higgs boson. An exhaustive and comprehensive treatment of the asymptotic freedom is included. The text eventually treats the internal structure of hadrons with focus on the Drell-Yan process and the ultra-relativistic photon-quark interaction.
