Hadron masses in QCD with one quark flavour

Hadron masses in QCD with one quark flavour

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≃4.4r0 (≃ 2.2 fm) at two different lattice spacings:...

Zusammenfassung: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≃4.4r0 (≃ 2.2 fm) at two different lattice spacings: a≃0.37r0 (≃ 0.19 fm) and a≃0.27r0 (≃ 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.
