exotic meson at light quark masses
J. N. Hedditch, W. Kamleh, B. G. Lasscock +3
The mass of the exotic meson, created with hybrid interpolating fields, is explored at light quark masses approaching 25 MeV (). Access to such light q…

Search for the pentaquark resonance signature in lattice QCD
B. G. Lasscock, J. Hedditch, D. B. Leinweber +5
Claims concerning the possible discovery of the Θ^+ pentaquark, with minimal quark content uudd\bar{s}, have motivated our comprehensive study into possible pentaquark states using…

Systematic uncertainties in the precise determination of the strangeness magnetic moment of the nucleon
D. B. Leinweber, S. Boinepalli, A. W. Thomas +4
Systematic uncertainties in the recent precise determination of the strangeness magnetic moment of the nucleon are identified and quantified. In summary, G_M^s = -0.046 \pm 0.019 μ…
