Lattice QCD calculation of the Compton amplitude subtraction function
K. U. Can, A. Hannaford-Gunn, R. Horsley +6
The Compton amplitude subtraction function is an essential component in work concerning both the proton radius puzzle and the proton-neutron mass difference. However, owing to the…

Towards nucleon structure function moments and parton momentum fractions from lattice QCD
K. U. Can, R. Horsley, P. E. L. Rakow +4
We calculate the lowest even isovector moment of the structure function in -flavour lattice QCD with varying quark masses corresponding to $m_Ï\approx [410, 360, 300] \…

Renormalisation Group Equations for 2+1 clover fermions
K. U. Can, R. Horsley, P. E. L. Rakow +4
Many lattice QCD simulations now have many lattice spacings available, and it is of interest to investigate how they scale. In this talk we first derive renormalisation group equat…
