Identifying CP Basis Invariants in SMEFT [PDF]

Building on our automated framework that uses ring diagrams for classifying CP basis invariants [1], this paper broadens the application of the methodology with more extensive examples and a wider scope of theoretical frameworks.

Threshold corrections in SMEFT

Journal of High Energy Physics
Threshold corrections provide a universal link between experimentally measured broken-phase parameters and MS ¯ $$ \overline{\mathrm{MS}} $$ renormalised symmetric-phase parameters used in SMEFT renormalisation-group (RG) analyses and matching to new ...

ATLAS EFT results in the top quark sector

SciPost Physics Proceedings
With no evidence of direct production of beyond the Standard Model (BSM) particles at the TeV scale, deviations from the Standard Model (SM) can be explored systematically through Effective Field Theories (EFTs) such as the Standard Model EFT (SMEFT ...

The $B$ Anomalies and non-SMEFT New Physics

, 2022
The modern viewpoint is that the Standard Model is the leading part of an effective field theory that obeys the symmetry $SU(3)_C \times SU(2)_L \times U(1)_Y$.

Mapping between γ 5 schemes in the Standard Model Effective Field Theory

Journal of High Energy Physics
We explore the relation between two distinct prescriptions for γ 5 in dimensional regularization — the Breitenlohner Maison t’Hooft Veltman (BMHV) scheme and Naive Dimensional Regularisation (NDR).

Dimension-8 SMEFT contact-terms for vector-pair production via on-shell Higgsing

Journal of High Energy Physics
We derive the dimension-8 standard-model effective theory (SMEFT) contact terms relevant for vector-pair production at the LHC and lepton colliders.
