Effective Field Theories in R_xi gauges
M. Misiak, M. Paraskevas, J. Rosiek +2
In effective quantum field theories, higher dimensional operators can affect the canonical normalization of kinetic terms at tree level. These contributions for scalars and gauge b…
The decay in the Standard-Model Effective Field Theory
A. Dedes, M. Paraskevas, J. Rosiek +2
Assuming that new physics effects are parametrized by the Standard-Model Effective Field Theory (SMEFT) written in a complete basis of up to dimension-6 operators, we calculate the…
Gauge fixing the Standard Model Effective Field Theory
Andreas Helset, Michael Paraskevas, Michael Trott
We gauge fix the Standard Model Effective Field Theory in a manner invariant under background field gauge transformations using a geometric description of the field connections.
Dirac and Majorana Feynman Rules with four-fermions
Michael Paraskevas
A compact method for amplitude calculations in theories with Dirac and Majorana effective operators is discussed. Using the renormalizable formalism of Denner et al., [1,2] for pro…
