Sigma resonance parameters from a lattice QCD simulation
R. Molina, D. Guo, A. Alexandru +2
In this work we present the analysis of the energy spectrum from a recent two-flavor () lattice QCD calculation for pion-pion scattering in the scalar, isoscalar channel (th…

Three-body spectrum in a finite volume: the role of cubic symmetry
M. Döring, H. -W. Hammer, M. Mai +3
The three-particle quantization condition is partially diagonalized in the center-of-mass frame by using cubic symmetry on the lattice. To this end, instead of spherical harmonics,…
