Journal ArticleDOI
Excited state baryon spectroscopy from lattice QCD
TL;DR: In this article, the Nucleon and Delta excited state spectra on dynamical anisotropic clover lattices were calculated and the first time this has been achieved in a lattice calculation.
Journal ArticleDOI

TL;DR: In this paper, the first light-hadron spectroscopy on a set of dynamical, anisotropic lattices was presented, and a convenient set of coordinates that parameterize the two-dimensional plane of light and strange-quark masses was introduced.
Journal ArticleDOI
Impulse approximation dirac optical potential
TL;DR: In this article, the impulse approximation to the Dirac optical potential for proton-nucleus elastic scattering is deduced from elementary considerations and found to be in remarkably good agreement with phenomenological parameters.
Journal ArticleDOI
Flavor structure of the excited baryon spectra from lattice QCD
TL;DR: In this paper, a lattice QCD for baryons that can be formed from quarks, namely the N-, ε, δ, ε and ε families, is presented.
Journal ArticleDOI
Relativistic impulse approximation for p nucleus elastic scattering
TL;DR: In this paper, an impulse-approximation Dirac optical potential (DOP) was used for the first time to calculate the optical potential of a single photon, with excellent agreement with T/sub p/ = 500 MeV p/sub pol + /sup 16/O and /sup 40/Ca.
