18 Sep 2002 | | Subject: | hep-lat | | Abstract: | We study the singlet and non-singlet scalar-meson masses using domain wall fermions and the quenched approximation. The singlet mass is found to be smaller than the non-singlet mass and indicates that the lowest singlet meson state could be lighter than 1 GeV. The two-point functions for very small quark masses are compared with expectations from the small-volume chiral perturbation theory and the presence of fermionic zero modes. | | Source: | arXiv, hep-lat/0209132 | | Services: | Forum | Review | PDF | Favorites | |
