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…
Renormalization Group Approach to Confinement
Gerrit Schierholz
While we have several complementary models of confinement, some of which are phenomenologically appealing, we do not have the ability to calculate analytically even simple aspects…
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…
Absence of CP Violation in the Strong Interaction: Vacuum thwarts Axion
Gerrit Schierholz
QCD admits a contribution to the action, the term, which potentially gives rise to nontrivial phases and violates CP. This is essentially a question of how the vacuum reacts to…
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…
