Future collider sensitivities to νSMEFT interactions

Journal of Physics G: Nuclear and Particle Physics
Abstract The discovery of neutrino oscillations and masses provides strong motivation to extend the Standard Model by including right-handed neutrinos, which lead to heavy neutrino states that could exist at the electroweak scale. These states may also be influenced by new high-scale, weakly interacting physics.

Missing energy plus jet in the SMEFT

Journal of High Energy Physics
Abstract We study the production of dineutrinos in proton-proton collisions, with large missing transverse energy and an energetic jet as the experimental signature. Recasting a search from the ATLAS collaboration we work out constraints on semileptonic four-fermion operators, gluon and electroweak dipole operators and Z-penguins ...

SMEFT Corrections to $Z$ Boson Decays

, 2018
We compute the one-loop corrections to $Z$ decay properties from dimension-6 operators in the Standard Model Effective Field Theory (SMEFT) that contribute also to anomalous 3-gauge boson couplings and examine the relative sensitivity of the two processes to the anomalous couplings.

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).

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 ...
