Renormalisation group effects on SMEFT interpretations of LHC data

Journal of High Energy Physics, 2023
We explore the impact of Renormalisation Group (RG) effects in the Standard Model Effective Field Theory (SMEFT) interpretations of LHC measurements.

Reactor neutrino oscillations as constraints on effective field theory

Journal of High Energy Physics, 2019
We study constraints on the Standard Model Effective Field Theory (SMEFT) from neutrino oscillations in short-baseline reactor experiments. We calculate the survival probability of reactor antineutrinos at the leading order in the SMEFT expansion, that ...

Higgs production from anomalous gluon dynamics

Journal of High Energy Physics
We present a two-loop analysis of the contributions to Higgs production via gluon-gluon fusion arising from the triple-gluon operator in the Standard Model effective field theory (SMEFT).

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

Journal 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,

SMEFT predictions for semileptonic processes

Physical Review D
The SU(2)L×U(1)Y invariance of the Standard Model effective field theory (SMEFT) predicts multiple restrictions in the space of Wilson coefficients of U(1)em invariant effective Lagrangians such as the low-energy effective field theory (LEFT), used for low-energy flavor physics observables, or the Higgs effective field theory (HEFT) in unitary gauge ...

Analytic results for electroweak precision observables at NLO in SMEFT

Journal of High Energy Physics
We present analytic results for electroweak precision observables (EWPO) at next-to-leading order (NLO) in dimension-six SMEFT, with no assumptions on the flavour structure of SMEFT Wilson coefficients. The results are given in five different electroweak

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 ...

Model dependence in SMEFT

We point out that, although SMEFT is constructed to be model-independent, this holds only if complete sets of operators are used. SMEFT analyses that focus on subsets of operators are only semi-model-independent. They probe classes of ultraviolet models, opening a window to the underlying new physics.
