Perturbative Gradient Flow for the nEDM and beyond: LEFT Short-Flow-Time Expansion and EW renormalization

by Oscar Lara Crosas (ETH Zürich)

Thursday 19 Mar 2026, 11:00 → 12:00 Europe/Amsterdam

Colloquium Room (Nikhef)

In this talk I will introduce the main perturbative aspects of the gradient flow formalism, and discuss our efforts to make a connection to lattice simulations for the neutron Electric Dipole Moment (nEDM). Lastly, I will present our recent progress on the Short-Flow-Time expansion of the QCD sector of the LEFT basis, and I will present the possibility of using the gradient flow to renormalize both LEFT and SMEFT by extending the formalism to the EW sector.
