Pentaquarks on the light front, and their mixture with baryons
Nicholas Miesch, Edward Shuryak, Ismail Zahed
In previous papers we developed the light front formulation for Hamiltonians and wave functions (WFs) for mesons and baryons, with both confinement and chiral symmetry breaking. Fo…

Pentaquarks made of light quarks and their admixture to baryons
Nicholas Miesch, Edward Shuryak, Ismail Zahed
This paper is a continuation of our studies of multiquark hadrons. The anti-symmetrization of their wavefunctions required by Fermi statistics is nontivial, as it mixes orbital, co…

D-shell mixing in light baryons and its effect on the orbital motion
Nicholas Miesch, Edward Shuryak, Ismail Zahed
The standard description of the nucleon in the non-relativistic quark model is an state without orbital motion. Yet, there are several indications from phenomenology that…
