Hidden simplicity in the scattering for neutron stars and black holes
Rafael Aoude, Andreas Helset
Heavy particle effective theory applied to spinning black holes provides a natural framework in which propagators linearize and numerators exponentiate. In this work, we exploit th…

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…

Geometry of soft scalars at one loop
Timothy Cohen, Ipak Fadakar, Andreas Helset +1
We extend the soft theorems for scattering amplitudes of scalar effective field theories to one-loop order. Our analysis requires carefully accounting for the fact that the soft li…
