Low-lying odd-parity nucleon resonances as quark-model like states
Curtis D. Abell, Derek B. Leinweber, Zhan-Wei Liu +2
Recent lattice QCD results for the low-lying odd-parity excitations of the nucleon near the and resonance positions have revealed that the lattice QCD s…
Structure of the Nucleon and its Excitations
Waseem Kamleh, Derek Leinweber, Zhan-wei Liu +4
The structure of the ground state nucleon and its finite-volume excitations are examined from three different perspectives. Using new techniques to extract the relativistic compone…
Spectroscopy with Local Multi-hadron Interpolators in Lattice QCD
Adrian L. Kiratidis, Waseem Kamleh, Derek B. Leinweber +3
The positive-parity nucleon spectrum is studied in 2 + 1 flavour lattice QCD in an attempt to discover novel low-lying energy eigenstates in the region of the Roper resonance. In t…
Search for low-lying lattice QCD eigenstates in the Roper regime
Adrian L. Kiratidis, Waseem Kamleh, Derek B. Leinweber +3
The positive-parity nucleon spectrum is explored in -flavour lattice QCD in a search for new low-lying energy eigenstates near the energy regime of the Roper resonance. In a…
Hamiltonian effective field theory study of the resonance in lattice QCD
Zhan-Wei Liu, Waseem Kamleh, Derek B. Leinweber +3
Drawing on experimental data for baryon resonances, Hamiltonian effective field theory (HEFT) is used to predict the positions of the finite-volume energy levels to be observed in…
N* Spectroscopy from Lattice QCD: The Roper Explained
Derek Leinweber, Waseem Kamleh, Adrian Kiratidis +6
This brief review focuses on the low-lying even- and odd-parity excitations of the nucleon obtained in recent lattice QCD calculations. Commencing with a survey of the 2014-15 lite…
