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…
A theory vade mecum for PSI experiments
Gilberto Colangelo, Franziska Hagelstein, Adrian Signer +1
This article gives a compact introduction and overview of the theory underlying the experiments described in the rest of this review.
Short-distance constraints for the longitudinal component of the hadronic light-by-light amplitude: an update
Gilberto Colangelo, Franziska Hagelstein, Martin Hoferichter +2
We reassess the impact of short-distance constraints for the longitudinal component of the hadronic light-by-light amplitude on the anomalous magnetic moment of the muon, $a_μ=(g-2…
A dispersive estimate of scalar contributions to hadronic light-by-light scattering
Igor Danilkin, Martin Hoferichter, Peter Stoffer
We consider the contribution of scalar resonances to hadronic light-by-light scattering in the anomalous magnetic moment of the muon. While the has already been addresse…
Effective field theory interpretation of lepton magnetic and electric dipole moments
Jason Aebischer, Wouter Dekens, Elizabeth E. Jenkins +3
We perform a model-independent analysis of the magnetic and electric dipole moments of the muon and electron. We give expressions for the dipole moments in terms of operator coeffi…
