Coulomb Gauge QCD and the Excited Hadron Spectrum
Felipe J. Llanes-Estrada, Stephen R. Cotanch, Tim van Cauteren +3
We discuss progress in understanding the light and heavy quark excited hadron spectrum from Coulomb gauge QCD. For light quark systems we highlight the insensitivity to spontaneous…
Strong coupling treatment of the polaronic system consisting of an impurity in a condensate
W. Casteels, T. Van Cauteren, J. Tempere +1
The strong coupling treatment of the Fröhlich-type polaronic system, based on a canonical transformation and a standard Landau-Pekar type variational wave function, is applied to t…
Regge-plus-resonance predictions for kaon photoproduction from the neutron
P. Vancraeyveld, L. De Cruz, J. Ryckebusch +1
We present predictions for n(gamma,K+)Sigma- differential cross sections and photon-beam asymmetries and compare them to recent LEPS data. We adapt a Regge-plus-resonance (RPR) mod…
Excited baryons as experimental probes of the quark mass
Felipe J. Llanes-Estrada, Pedro Bicudo, Marco Cardoso +1
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 vali…
Probing the infrared quark mass from highly excited baryons
P. Bicudo, M. Cardoso, T. Van Cauteren +1
We argue 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 u…
Parity doubling in the high baryon spectrum: near-degenerate three-quark quartets
Felipe J. Llanes-Estrada, Pedro Bicudo, Marco Cardoso +1
We report on the first calculation of excited baryons with a chirally symmetric Hamiltonian, modeled after Coulomb gauge QCD (or upgraded from the Cornell meson potential model to…
