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…
Probing the proton and its excitations in full QCD
Benjamin J. Owen, Waseem Kamleh, Derek B. Leinweber +2
We present a first look at the application of variational techniques for the extraction of the electromagnetic properties of an excited nucleon system. In particular, we include pr…
Visualisations of coherent centre domains in local Polyakov loops
Finn M. Stokes, Waseem Kamleh, Derek B. Leinweber
Quantum Chromodynamics exhibits a hadronic confined phase at low to moderate temperatures and, at a critical temperature , undergoes a transition to a deconfined phase known a…
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…
Electromagnetic Form Factors for the (1405)
Benjamin J. Menadue, Waseem Kamleh, Derek B. Leinweber +2
Building on our successful technique to isolate the otherwise-elusive (1405) using correlation matrix techniques and multiple source and sink smearings, we present calculations…
Searching for low-lying multi-particle thresholds in lattice spectroscopy
M. Selim Mahbub, Waseem Kamleh, Derek B. Leinweber +1
We explore the Euclidean-time tails of odd-parity nucleon correlation functions in a search for the S-wave pion-nucleon scattering-state threshold contribution. The analysis is per…
