| Summary: | 碩士 === 國立臺灣大學 === 應用物理研究所 === 105 === Quantum Chromodynamics (QCD) is the fundamental theory for the strong interaction inside the nucleus, and lattice QCD (formulating QCD on a discrete space-time lattice) is the most viable way to solve QCD nonperturbatively from the first principles. In this thesis, using the quark propagators computed by Professor Ting-Wai Chiu, we perform an exploratory study of the hadron mass spectrum in lattice QCD with optimal domain-wall fermion, in 2-flavors QCD on the 243 × 48 lattice. Even the pion masses of these gauge ensembles are unphysically heavy, after extrapolation to Mπ = 140 MeV, the mass spectra of the mesons and baryons containing charm and strange quarks are in good agreement with the high energy experimental results.
