【 摘 要 】

Elementary Particle Physics is based on studies of the fundamental building blocks of nature and their interactions. The Standard Model of Particle Physics is the most complete and successful theory to describe all observed particle phenomena. It has also made successful quantitative predictions for interaction rates and couplings, as well as for the existence of particles such as the t neutrino and the top quark, that were observed subsequently. The latter was found in 1995 at Fermi National Accelerator Laboratory (Fermilab) by the CDF and DO collaborations. In spite of the tremendous success of the Standard Model, we know that it is incomplete. To name a few shortcomings, the Standard Model does not include gravity, does not provide explanations for the choice of its parameters, does not account for dark matter and dark energy, and there is the notorious fine-tuning problem due to radiative corrections to the Higgs-boson mass. While the Standard Model successfully unifies the electromagnetic and the weak interactions, the strong and the gravitational forces are still decoupled. For decades, the ultimate goal of particle physics has been to unify all interactions in one Grand Unified Theory.
