Mapping chiral symmetry breaking in the excited baryon spectrum

Understand

We study the conjectured "Insensitivity to Chiral Symmetry Breaking" in the highly excited light baryon spectrum.

• While the experimental spectrum is being measured at JLab and CBELSA/TAPS, this insensitivity remains to be computed theoretically in detail.
• As the only existing option to have both confinement, highly excited states and chiral symmetry, we adopt the truncated Coulomb gauge formulation of QCD, considering a linearly confining Coulomb term.
• Adopting a systematic and numerically intensive variational treatment up to 12 harmonic oscillator shells we are able to access several angular and radial excitations.
