Excited hadrons in n_f=2 QCD
G. Engel, C. Gattringer, C. B. Lang +3
The chirally improved (CI) fermion action allows us to obtain results for pion masses down to 320 MeV on (in lattice units) comparatively small lattices with physical extent of 2.4…
Spectroscopy of light tetraquark states
S. Prelovsek, T. Draper, C. B. Lang +4
We address the question whether the lightest scalar mesons sigma and kappa are tetraquarks, as is strongly supported by many phenomenological studies. We present a search for possi…
The chiral and angular momentum content of the rho-meson
Leonid Ya. Glozman, C. B. Lang, Markus Limmer
It is possible to define and calculate in a gauge-invariant manner the chiral as well as the partial wave content of the quark-antiquark Fock component of a meson in the infrared,…
Canonical fermion determinants in lattice QCD - Numerical evaluation and properties
Erek Bilgici, Julia Danzer, Christof Gattringer +2
We analyze canonical fermion determinants, i.e., fermion determinants projected to a fixed quark number q. The canonical determinants are computed using a dimensional reduction for…
Angular momentum content of the rho-meson in lattice QCD
Leonid Ya. Glozman, C. B. Lang, Markus Limmer
The variational method allows one to study the mixing of interpolators with different chiral transformation properties in the non-perturbatively determined physical state. It is th…
Comparison of filtering methods in SU(3) lattice gauge theory
F. Bruckmann, F. Gruber, C. B. Lang +4
We systematically compare filtering methods used to extract topological excitations from lattice gauge configurations. We show that there is a strong correlation of the topological…
