One-loop matching of the -odd three-gluon operator to the gradient flow
Òscar L. Crosas, Christopher J. Monahan, Matthew D. Rizik +2
The calculation of the neutron electric dipole moment within effective field theories for physics beyond the Standard Model requires non-perturbative hadronic matrix elements of ef…
Two-loop matching of the chromo-magnetic dipole operator with the gradient flow
J. Borgulat, R. Harlander, M. D. Rizik +1
The chromo-magnetic dipole operator is expressed in terms of operators at finite flow time in the gradient-flow formalism. The matching coefficients are evaluated through next-to-n…
A novel nonperturbative renormalization scheme for local operators
Anna Hasenfratz, Christopher J. Monahan, Matthew D. Rizik +2
The gradient flow exponentially suppresses ultraviolet field fluctuations and removes ultraviolet divergences (up to a multiplicative fermionic wavefunction renormalization). It ca…
One-loop matching for quark dipole operators in a gradient-flow scheme
Emanuele Mereghetti, Christopher J. Monahan, Matthew D. Rizik +2
The quark chromoelectric dipole (qCEDM) operator is a CP-violating operator describing, at hadronic energies, beyond-the-standard-model contributions to the electric dipole moment…
Nonperturbative Renormalization of the Quark Chromoelectric Dipole Moment with the Gradient Flow:Power Divergences
Jangho Kim, Thomas Luu, Matthew D. Rizik +1
The CP-violating quark chromoelectric dipole moment (qCEDM) operator, contributing to the electric dipole moment (EDM), mixes under renormalization and particularly on the lattice…
Short flow-time coefficients of CP-violating operators
Matthew D. Rizik, Christopher J. Monahan, Andrea Shindler
Measurements of a permanent neutron electric dipole moment (EDM) potentially probe Beyond-the-Standard Model (BSM) sources of CP-violation. At low energy the CP-violating BSM inter…
Renormalization of CP-Violating Pure Gauge Operators in Perturbative QCD Using the Gradient Flow
Matthew Rizik, Christopher Monahan, Andrea Shindler
We use the Yang-Mills gradient flow to study the mixing of CP-violating pure gauge operators in continuum QCD with special attention to Weinberg's d=6 purely gluonic operator. The…
