Excited baryons as experimental probes of the quark mass

We observe that excited hadrons provide an opportunity to probe from experiment the power-law running of the quark mass in the mid infrared, while the condition m(k) < k remains valid. A relatively clean analysis is possible for the maximum spin excitations of the Delta baryons accessible at current experimental facilities such as ELSA and Jlab.

Probing the infrared quark mass from highly excited baryons.
It is argued that three-quark excited states naturally group into quartets, split into two parity doublets, and that the mass splittings between these parity partners decrease higher up in the baryon spectrum, and a measurement of masses of high-partial-wave Delta* resonances should be sufficient to unambiguously establish the approximate degeneracy.

Analytic properties of the Landau gauge gluon and quark propagators
We explore the analytic structure of the gluon and quark propagators of Landau gauge QCD from numerical solutions of the coupled system of renormalized Dyson-Schwinger equations and from fits toExpand
Propagator of the Lattice Domain Wall Fermion and the Staggered Fermion
We calculate the propagator of the domain wall fermion (DWF) of the RBC/UKQCD collaboration with 2 + 1 dynamical flavors of 163 × 32 × 16 lattice in Coulomb gauge, by applying the conjugate gradientExpand
