Renormalizing Two-Fermion Operators in the SMEFT via Supergeometry
Benoît Assi, Andreas Helset, Julie Pagès +1
We extend the geometric framework of field-space covariance for loop computations, thereby unifying the treatment of scalars, fermions, and gauge bosons in effective field theories…

Fermion Geometry and the Renormalization of the Standard Model Effective Field Theory
Benoît Assi, Andreas Helset, Aneesh V. Manohar +2
The geometry of field space governs on-shell scattering amplitudes. We formulate a geometric description of effective field theories which extends previous results for scalars and…
