Low-Lying Nucleons from Chirally Improved Fermions
D. Broemmel, P. R. Crompton, C. Gattringer +4
We report on our preliminary results on the low-lying excited nucleon spectra which we obtain through a variational basis formed with three different interpolators.

Excited nucleons with chirally improved fermions
Dirk Broemmel, Peter Crompton, Christof Gattringer +4
We study positive and negative parity nucleons on the lattice using the chirally improved lattice Dirac operator. Our analysis is based on a set of three operators chi_i with the n…
