Electromagnetic Form Factors of Nucleon Excitations in Lattice QCD
Finn M. Stokes, Waseem Kamleh, Derek B. Leinweber +1
Variational analysis techniques in lattice QCD are powerful tools that give access to the full spectrum of QCD. At zero momentum, these techniques are well established and can clea…
The Light-Quark Magnetic Moment of the Lambda(1405) Antikaon-Nucleon Molecule
Jonathan M. M. Hall, Waseem Kamleh, Derek B. Leinweber +3
The light-quark sector of the Lambda(1405) baryon is examined in the context of the recent discovery of a dominant antikaon-nucleon composition at low quark masses. Further evidenc…
Electromagnetic Form Factors of Excited Nucleons via Parity-Expanded Variational Analysis
Finn M. Stokes, Waseem Kamleh, Derek B. Leinweber +1
Variational analysis techniques in lattice QCD are powerful tools that give access to the excited state spectrum of QCD. At zero momentum, these techniques are well established and…
Light-quark contributions to the magnetic form factor of the Lambda(1405)
Jonathan M. M. Hall, Waseem Kamleh, Derek B. Leinweber +3
In a recent study of the Lambda(1405), the suppression of the strange-quark contribution to the magnetic form factor was interpreted as the discovery of a dominant antikaon-nucleon…
Transition of in Lattice QCD
Benjamin J. Owen, Waseem Kamleh, Derek B. Leinweber +2
With the ongoing experimental interest in exploring the excited hadron spectrum, evaluations of the matrix elements describing the formation and decay of such states via radiative…
Light Meson Form Factors at near Physical Masses
Benjamin Owen, Waseem Kamleh, Derek Leinweber +2
The ability for most hadrons to decay via strong interactions prevents the direct measurement of their electromagnetic properties. However, a detailed understanding of how these re…
