Unusual Path to High Energy Physics: From Madagascar Bush World Class Scientist

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 the ShifmanVainshtein-Zakharov (SVZ) approach. Provided that the method is used carefully, one can predict succesfully all hadron masses and couplings, the size of the quark masses and of the QCD condensates and coupling.The collection of research works is closed by some author's analysis of the COVID19 in Madagascar. The rest of the book mentions the author's social activities: Organization of the QCDMontpellier (FR) and HEPMAD-Antananarivo (MG) Conference Series, Popularization and Development of HEP and some author's Political and Social Engagements in Madagascar.
