Finite-volume energy spectrum of the system
Andrei Alexandru, Ruairí Brett, Chris Culver +4
The dynamics of multi-kaon systems are of relevance for several areas of nuclear physics. However, even the simplest systems, two and three kaons, are hard to prepare and study exp…
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…
Extraction of isoscalar phase-shifts from lattice QCD
Dehua Guo, Andrei Alexandru, Raquel Molina +2
We conduct a two-flavor () lattice QCD calculation of the elastic phase-shifts for pion-pion scattering in the scalar, isoscalar channel (the -meson). The calculation is…
Role of the strange quark in the rho(770) meson
R. Molina, D. Guo, B. Hu +2
Recently, the GWU lattice group has evaluated high-precision phase-shift data for scattering in the , channel. Unitary Chiral Perturbation Theory describes thes…
Rho resonance parameters from lattice QCD
Dehua Guo, Andrei Alexandru, Raquel Molina +1
We perform a high-precision calculation of the phase shifts for - scattering in the I = 1, J = 1 channel in the elastic region using elongated lattices with two mass-degenera…
Resonance Parameters for the rho-meson from Lattice QCD
Dehua Guo, Andrei Alexandru
We present a calculation of the phase-shift for - scattering in isospin-1, spin-1 channel in the elastic region. The mass and width of the rho resonance is extracted by fitti…
