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.

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

Journal 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.

NNLO event generation for pp → Zh → ℓ + ℓ − b b ¯ $$ pp\to Zh\to {\mathrm{\ell}}^{+}{\mathrm{\ell}}^{-}b\overline{b} $$ production in the SM effective field theory

Journal of High Energy Physics, 2022
We consider associated Zh production with Z → ℓ + ℓ − and h → b b ¯ $$ h\to b\overline{b} $$ decays in hadronic collisions. In the framework of the Standard Model effective field theory (SMEFT) we calculate the QCD corrections to this process and achieve

A Monte Carlo global analysis of the Standard Model Effective Field Theory: the top quark sector

Journal of High Energy Physics, 2019
We present a novel framework for carrying out global analyses of the Standard Model Effective Field Theory (SMEFT) at dimension-six: SMEFiT. This approach is based on the Monte Carlo replica method for deriving a faithful estimate of the experimental and

The Global Electroweak and Higgs Fits in the LHC era

, 2017
We update the global fit to electroweak precision observables, including the effect of the latest measurements at hadron colliders of the $W$ and top-quark masses and the effective leptonic weak mixing angle.

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 ...

The Neutrino Option

, 2017
The minimal seesaw scenario can radiatively generate the Higgs potential to induce electroweak symmetry breaking while supplying an origin of the Higgs vacuum expectation value from an underlying Majorana scale.

Global fit to $b \to c \tau \nu$ transitions

, 2019
We perform a general model-independent analysis of $b \to c \tau \bar{\nu}_\tau $ transitions, including measurements of $\mathcal{R}_D$, $\mathcal{R}_{D^*}$, their $q^2$ differential distributions, the recently measured longitudinal $D^*$ polarization ...
