The author starts by counting his unsual path to High-Energy Physics (HEP) and gives a brief introduction to the field. Then, he collects his different original research works from the low-energy precision test of the Standard Model (SM) via the anomalous magnetic moment of leptons to the search for new physics at some high energy accelerators.The remaining parts of the book focus on the non-perturbative aspects of Quantum ChromoDynamics (QCD) within...
