Scattering processes and resonances from lattice QCD
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 …

[HTML][HTML] Aharonov–Bohm effect and nucleon–nucleon phase shifts on the lattice
PF Bedaque - Physics Letters B, 2004 - Elsevier
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 …

Insight into the scalar mesons from a lattice calculation
We study the possibility that the light scalar mesons are q ̄ 2q 2 states rather than q ̄ q.
