TL;DR: In this article, the authors reported the results of the calculation of the hadron spectrum in the quenched approximation on a 16∗∗3 × 48 lattice with a RG improved gauge action and the Wilson quark action.
Abstract: I report the results of the calculation of the hadron spectrum in the quenched approximation on a 16∗∗3 × 48 lattice with a RG improved gauge action and the Wilson quark action: i) The masses of the π and ϱ mesons are calculated up to the point m π / m ϱ ≌ 0.38 . The results show that there exists a smooth limit K→K C for the meson masses. However, the mass of N is determined only up to the point m π / m ϱ ≌0.61 ; ii) We also calculated the masses of hadrons which are composed of different kinds of quarks. If we use, when extrapolating the results to the physical ones, phenomenological mass formula which take into account the hyperfine splitting term, all the masses of low lying flavor non-singlet hadrons agree with experimental values within one-standard deviation. In particular, the mass of σ turns out to be about 100 MeV larger than that of λ, in accord with experements; iii) We find that the H-dibaryon is below the σσ threshold for strong decay. Furthermore the case where the H is slightly below the NN threshold for weak decay is consistent with our numerical results and is not conflict with the stability of nucleus.
