Exploring the Roper wave function in Lattice QCD
Waseem Kamleh, Derek B. Leinweber, Dale S. Roberts
Using a correlation matrix analysis consisting of a variety of smearings, the CSSM Lattice collaboration has successfully isolated states associated with the Roper resonance and ot…
Nucleon Excited State Wave Functions from Lattice QCD
Dale S. Roberts, Waseem Kamleh, Derek B. Leinweber
We apply the eigenvectors from a variational analysis to successfully extract the wave functions of even-parity excited states of the nucleon, including the Roper. We explore the f…
Quark Propagation in the Instantons of Lattice QCD
Amalie Trewartha, Waseem Kamleh, Derek Leinweber +1
We quantitatively examine the extent to which instanton degress of freedom, contained within standard Monte-carlo generated gauge-field configurations, can maintain the characteris…
Wave Function of the Roper from Lattice QCD
Dale S. Roberts, Waseem Kamleh, Derek B. Leinweber
We apply the eigenvectors from a variational analysis in lattice QCD to successfully extract the wave function of the Roper state, and a higher mass P_11 state of the nucleon. We u…
