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…
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] \…
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…
Lattice gauge ensembles and data management
Yasumichi Aoki, Ed Bennett, Ryan Bignell +13
We summarize the status of lattice QCD ensemble generation efforts and their data management characteristics. Namely, these proceedings combine the contributions to a dedicated par…
