ALP–SMEFT Interference

Anne Galda , Institute of Physics (WA THEP), Mainz

The Standard Model Effective Field Theory (SMEFT) provides a systematic framework to parametrize the low-energy effects of unknown heavy particles. In this talk I will show that in the presence of additional light particles such as ax-ions and ALPs interacting with the Standard Model (SM) via non-renormalizable dimension-6 operators, SMEFT Wilson coefficients are generated by means of one-loop order renormalization group (RG) evolution equations. This yields additional contributions to low-energy observables which I will discuss for the case of the top chromo-magnetic dipole moment to lowest logarithmic order.
