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…

Electric Dipole Moment Results from lattice QCD

Jack Dragos, Thomas Luu, Andrea Shindler +1

We utilize the gradient flow to define and calculate electric dipole moments induced by the strong QCD -term and the dimension-6 Weinberg operator. The gradient flow is a promis…

Electromagnetic form factors at large momenta from lattice QCD

A. J. Chambers, J. Dragos, R. Horsley +10

Accessing hadronic form factors at large momentum transfers has traditionally presented a challenge for lattice QCD simulations. Here we demonstrate how a novel implementation of t…

Nucleon matrix elements using the variational method in lattice QCD

Jack Dragos, Roger Horsley, Waseem Kamleh +6

The extraction of hadron matrix elements in lattice QCD using the standard two- and three-point correlator functions demands careful attention to systematic uncertainties. One of t…

Improved determination of hadron matrix elements using the variational method

Jack Dragos, Roger Horsley, Waseem Kamleh +6

The extraction of hadron form factors in lattice QCD using the standard two- and three-point correlator functions has its limitations. One of the most commonly studied sources of s…

Variational Approach to the Calculation of gA

Benjamin J. Owen, Jack Dragos, Waseem Kamleh +4

We present a lattice QCD calculation of the nucleon axial charge, gA, using a variational approach. After a brief outline of how the variational method is applied to the calculatio…
