Gross-Llewellyn Smith sum rule from lattice QCD

K. Utku Can, Joshua A. Crawford, Roger Horsley +6

We compute the Gross-Llewellyn Smith sum rule, i.e. the lowest odd moment of the parity-violating structure function, , of the nucleon from a lattice QCD calculation of the Co…

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_π\approx [410, 360, 300] \…

Transverse force distributions in the proton from lattice QCD

J. A. Crawford, K. U. Can, R. Horsley +5

Single-spin asymmetries observed in polarised deep-inelastic scattering are important probes of hadron structure. The Sivers asymmetry has been the focus of much attention in QCD p…

Transverse force distributions in the proton from lattice QCD

K. U. Can, J. A. Crawford, R. Horsley +5

Single-spin asymmetries observed in polarised deep-inelastic scattering are important probes of hadron structure. The Sivers asymmetry provides information about the transverse mom…

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…
