Bjorken sum rule down to the elastic region from the lattice
J. A. Crawford, A. Hannaford-Gunn, R. Horsley +6
We present a lattice determination of the Bjorken sum rule via a Feynman-Hellmann calculation of the polarised forward Compton amplitude. We evaluate the lowest moment of the nucle…
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 th…
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] \;…
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…
Fourier Accelerated HMC in the SU(N) X SU(N) Principal Chiral Model
Roger Horsley, Pablo Morande, Brian Pendleton
We report the results of Fourier-accelerated HMC simulations of 2D SU(N) X SU(N) principal chiral models for N = 2, 3, 4, 6, 9. These models share several key properties with 4D QC…
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…
