The phase-shift of isospin-2 pi-pi scattering from lattice QCD
The phase-shift of isospin-2 pi-pi scattering lattice QCD
2011/1/7
Finite-volume lattice QCD calculations offer the possibility of extracting resonance parameters from the energy-dependent elastic phase-shift computed using the Luescher technique. In this letter, as ...
The pion-pion scattering phase shift is computed using LapH propagators. The LapH method for computing quark propagators is used to form two-particle correlation functions with a number of different o...
