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…
Variational Approach to the Calculation of gA
Benjamin J. Owen, Jack Dragos, Waseem Kamleh +4
We present a lattice QCD calculation of the nucleon axial charge, gA, using a variational approach. After a brief outline of how the variational method is applied to the calculatio…
Finite-volume corrections to charge radii
J. M. M. Hall, D. B. Leinweber, B. J. Owen +1
The finite-volume nature of lattice QCD entails a variety of effects that must be handled in the process of performing chiral extrapolations. Since the pion cloud that surrounds ha…
