Abstract
We invalidate the arguments given in [T.Yamazaki and Y.Kuramashi, Phys. Rev. D96, 114511 (2017)] over the HAL QCD method for hadron-hadron interactions on the lattice. We also pose questions on the practical usefulness of the method proposed in this reference.
Highlights
We invalidate the arguments given in [T
In a recent article [1], Yamazaki and Kuramashi present a theoretical analysis on the “relation between scattering amplitude and Bethe-Salpeter wave function in quantum field theory.”
This subject is important for hadron-hadron interactions in lattice QCD simulations and is closely related to the physics of multihadron systems such as the exotic resonances and the atomic nuclei
