RGE effects on new physics searches via gravitational waves

open access: yesJournal 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 ...

Theoretical developments in the SMEFT at dimension-8 and beyond

open access: yes, 2022
In this contribution to the Snowmass 2021 process we review theoretical developments in the Standard Model Effective Field Theory (SMEFT) with a focus on effects at the dimension-8 level and beyond.

Constraints on standard model effective field theory for a Higgs boson produced in association with W or Z bosons in the H → b b ¯ $$ \textrm{b}\overline{\textrm{b}} $$ decay channel in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics
A standard model effective field theory (SMEFT) analysis with dimension-six operators probing nonresonant new physics effects is performed in the Higgs-strahlung process, where the Higgs boson is produced in association with a W or Z boson, in proton ...

SMEFT probes in future precision DIS experiments [PDF]

open access: yes, 2023
We analyze the potential of future high-energy deep-inelastic scattering (DIS) experiments to probe new physics within the framework of the Standard Model Effective Field Theory (SMEFT).

Probing the flavour-blind SMEFT: EFT validity and the interplay of energy scales

open access: yesJournal of High Energy Physics
The Standard Model Effective Field Theory (SMEFT) offers a systematic approach to study potential deviations from the Standard Model (SM) through higher-dimensional operators that encapsulate new physics effects.

Low-energy effective field theory below the electroweak scale: operators and matching

open access: yesJournal of High Energy Physics, 2018
The gauge-invariant operators up to dimension six in the low-energy effective field theory below the electroweak scale are classified. There are 70 Hermitian dimension-five and 3631 Hermitian dimension-six operators that conserve baryon and lepton number,

Going beyond Top EFT

open access: yesJournal 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 ...

Future DUNE constraints on EFT

open access: yesJournal 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 ...

Interpreting W mass measurements in the SMEFT [PDF]

open access: yes, 2016
Measurements of the W± mass (mW) provide an important consistency check of the Standard Model (SM) and constrain the possibility of physics beyond the SM.
