RGE effects on new physics searches via gravitational waves

Journal of High Energy Physics
Gravitational wave (GW) observations offer a promising probe of new physics associated with a first-order electroweak phase transition. Precision studies of the Higgs potential, including Fisher matrix analyses, have been extensively conducted in this ...

Future DUNE constraints on EFT

Journal of High Energy Physics, 2018
In the near future, fundamental interactions at high-energy scales may be most efficiently studied via precision measurements at low energies. A universal language to assemble and interpret precision measurements is the so-called SMEFT, which is an ...

Going beyond Top EFT

Journal of High Energy Physics
We present a new way to interpret Top Standard Model measurements going beyond the SMEFT framework. Instead of the usual paradigm in Top EFT, where the main effects come from tails in momenta distributions, we propose an interpretation in terms of new ...

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 ...

Threshold corrections in SMEFT

Threshold corrections provide a universal link between experimentally measured broken-phase parameters and $\overline{\hbox{MS}}$ renormalised symmetric-phase parameters used in SMEFT renormalisation-group (RG) analyses and matching to new-physics models.

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 ...

Total Drell–Yan in the flavorful SMEFT

The European Physical Journal C
Abstract We perform a global analysis of Drell–Yan production of charged leptons and dineutrinos, the latter in missing energy plus jet events, in proton–proton collisions within the Standard Model Effective Field Theory (SMEFT). The combination allows for the removal of flat directions, sharper limits and to probe more couplings than the ...

Staying on top of SMEFT-likelihood analyses

SciPost Physics
We present a new global SMEFT analysis of LHC data in the top sector. After updating our set of measurements, we show how public ATLAS likelihoods can be incorporated into an external global analysis and how our analysis benefits from the additional information.

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).
