Improving the electromagnetic form factor of the pion at large using the Feynman-Hellmann theorem
K. U. Can, J. A. Crawford, R. Horsley +7
At large momentum transfer, it becomes increasingly difficult to access the form factor of the pion using lattice QCD simulations. Two of the limiting factors include t…
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…
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] \…
Multi-nucleon matrix elements on the lattice with the Feynman-Hellmann theorem
N. Humphrey, K. U. Can, R. Horsley +5
This work presents the first calculation of the lowest moment of the forward Compton structure function for a multi-nucleon deuteron-like state using Feynman-Hellma…
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…
