Physical interpretation of the 2s excitation of the nucleon
Finn M. Stokes, Waseem Kamleh, Derek B. Leinweber +1
Lattice QCD calculations of the radial excitation of the nucleon place the state at an energy of approximately 1.9 GeV, raising the possibility that it is associated with the…

Odd-Parity Nucleon Electromagnetic Transitions in Lattice QCD
Finn M. Stokes, Benjamin J. Owen, Waseem Kamleh +1
The parity-expanded variational analysis (PEVA) technique enables the isolation of opposite-parity eigenstates at finite momentum. The approach has been used to perform the first l…
