N* Spectrum using an O(a)-Improved Fermion Action
LHPC Collaboration · UKQCD Collaboration · D. G. Richards (Jefferson Laboratory and Old Dominion University)
Abstract
The construction of operators and calculational methods for the determination of the N* spectrum are discussed. The masses of the parity partners of the nucleon and delta are computed from the O(a)-improved data of the UKQCD Collaboration, and a clear splitting observed between the mass of the nucleon and its parity partner.
