摘要：
One-flavour QCD - a gauge theory with SU(3) colour gauge group and a fermion in the fundamental representation - is studied by Monte Carlo simulations. The mass spectrum of the hadronic bound states is investigated in a volume with extensions of L similar or equal to 4.4r(0) (similar or equal to 2.2 fm) at two different lattice spacings: a similar or equal to 0.37r(0) (similar or equal to 0.19 fm) and a similar or equal to 0.27r(0) (similar or equal to 0.13 fm). The lattice action is a Symanzik tree-level improved Wilson action for the gauge field and an (unimproved) Wilson action for the fermion.
