Three pion spectrum in the channel from lattice QCD
Chris Culver, Maxim Mai, Ruairí Brett +2
Three-body states are critical to the dynamics of many hadronic resonances. We show that lattice QCD calculations have reached a stage where these states can be accurately resolved…
Three-body unitarity versus finite-volume spectrum from lattice QCD
M. Mai, M. Döring, C. Culver +1
Strong three-body interactions above threshold govern the dynamics of many exotics and conventional excited mesons and baryons. Three-body finite-volume energies calculated from la…
A cross-channel study of pion scattering from lattice QCD
Maxim Mai, Chris Culver, Andrei Alexandru +2
We use a chiral model for pion interactions, in the inverse amplitude formalism, to perform a simultaneous analysis of lattice QCD results for pion-pion scattering in all three iso…
Pion scattering in the isospin I=2 channel from elongated lattices
C. Culver, M. Mai, A. Alexandru +2
Pion-pion elastic scattering in the isospin I=2 channel is investigated in two-flavor dynamical lattice QCD. Six ensembles are used with lattices elongated in one of the spatial di…
