Chiral susceptibility and axial U(1) anomaly near the (pseudo-)critical temperature
S. Aoki, Y. Aoki, H. Fukaya +6
We investigate relations between the chiral susceptibility and axial anomaly in lattice QCD at high temperatures. Employing the exactly chiral symmetric Dirac operator, we s…
The Compton amplitude and nucleon structure functions in lattice QCD
K. U. Can, M. Batelaan, A. Hannaford-Gunn +8
The structure of hadrons relevant for deep-inelastic scattering are completely characterised by the Compton amplitude. A direct calculation of the Compton amplitude in a lattice QC…
Feynman--Hellmann approach to transition matrix elements and quasi-degenerate energy states
M. Batelaan, K. U. Can, R. Horsley +6
The Feynman--Hellmann approach to computing matrix elements in lattice QCD by first adding a perturbing operator to the action is described using the transition matrix and the Dyso…
Weak decay constants of the neutral pseudoscalar mesons from lattice QCD+QED
Z. R. Kordov, R. Horsley, W. Kamleh +7
With increasing requirements for greater precision, it becomes essential to describe the effects of isospin breaking induced by both quark masses and electro-magnetic effects. In t…
Constraining beyond the Standard Model nucleon isovector charges
R. E. Smail, M. Batelaan, R. Horsley +8
At the TeV scale, low-energy precision observations of neutron characteristics provide unique probes of novel physics. Precision studies of neutron decay observables are susceptibl…
