The vast majority of hadrons observed in nature are not stable under the strong interaction;
rather they are resonances whose existence is deduced from enhancements in the energy …

The extraction of two-and three-body hadronic scattering amplitudes and the properties of
the low-lying hadronic resonances from the finite-volume energy levels in lattice QCD …

Many low energy hadrons, such as the rho, can be observed as resonances in scattering
experiments. A proposal by Lüscher enables one to determine infinite volume elastic …

The two-body decay rate of a weakly decaying particle (such as the kaon) is shown to be
proportional to the square of a well-defined transition matrix element in finite volume …

The ab initio understanding of hadronic three-body systems above threshold, such as exotic
resonances or the baryon spectrum, requires the mapping of the finite-volume eigenvalue …

We propose a method for the lattice QCD computation of nucleon–nucleon low-energy
interactions. It consists in simulating QCD in the background of a “electromagnetic” field …

We study the possibility that the light scalar mesons are q ̄ 2q 2 states rather than q ̄ q.
We perform a lattice QCD calculation of pseudoscalar meson scattering amplitudes, ignoring …

Strong three-body interactions above threshold govern the dynamics of many exotics and
conventional excited mesons and baryons. Three-body finite-volume energies calculated …

A lattice QCD calculation of s-wave hadron scattering lengths in the channels π-π, π-N, KN,
KN, and NN is carried out in the quenched approximation at β= 6/g 2= 5.7. A variant of the …

Using a quantum mechanical model, the exact energy eigenstates for two-particle two-
channel scattering are studied in a cubic box with periodic boundary conditions in all three …
