Confirming the Existence of the strong CP Problem in Lattice QCD with the Gradient Flow
Jack Dragos, Thomas Luu, Andrea Shindler +2
We calculate the electric dipole moment of the nucleon induced by the QCD theta term. We use the gradient flow to define the topological charge and use flavors of dynam…
Expansion coefficient of the pseudo-scalar density using the gradient flow in lattice QCD
J. G. Reyes, J. Dragos, J. Kim +2
We use the Yang-Mills gradient flow to calculate the pseudo-scalar expansion coefficient . This quantity is a key ingredient to obtaining the chiral condensate and stra…
Towards a determination of the nucleon EDM from the quark chromo-EDM operator with the gradient flow
Jangho Kim, Jack Dragos, Andrea Shindler +2
In this proceedings, we lay the foundation for computing the contribution of quark chromo-electric dipole moment (qCEDM) operator to the nucleon electric dipole moment. By applying…
Improvements to Nucleon Matrix Elements within a Vacuum from Lattice QCD
Jack Dragos, Thomas Luu, Andrea Shindler +2
Using the gradient flow, we calculated the nucleon mixing angle and the nucleon electric dipole moment (EDM) induced by the QCD -term. To do so, we computed the topologi…
