An Algebraic Formula for Two Loop Renormalization of Scalar Quantum Field Theory
Elizabeth E. Jenkins, Aneesh V. Manohar, Luca Naterop +1
We find a general formula for the two-loop renormalization counterterms of a scalar quantum field theory with interactions containing up to two derivatives, extending 't~Hooft's on…
Renormalization of the Standard Model Effective Field Theory from Geometry
Andreas Helset, Elizabeth E. Jenkins, Aneesh V. Manohar
-matrix elements are invariant under field redefinitions of the Lagrangian. They are determined by geometric quantities such as the curvature of the field-space manifold of scal…
Geometry in Scattering Amplitudes
Andreas Helset, Elizabeth E. Jenkins, Aneesh V. Manohar
We formulate the field-space geometry for an effective field theory of scalars and gauge bosons. Geometric invariants such as the field-space curvature enter in both scattering amp…
Dark Matter Effective Field Theory and an Application to Vector Dark Matter
Jason Aebischer, Wolfgang Altmannshofer, Elizabeth E. Jenkins +1
The Standard Model Effective Field Theory (SMEFT) and the Low Energy Effective Field Theory (LEFT) can be extended by adding additional spin 0, 1/2 and 1 dark matter particles whic…
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…
Non-Perturbative Effects in
Wouter Dekens, Elizabeth E. Jenkins, Aneesh V. Manohar +1
We compute the non-perturbative contribution of semileptonic tensor operators to the purely leptonic process and to the electr…
