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).

The decay $h\to \gamma\gamma$ in the Standard-Model Effective Field Theory

, 2018
Assuming that new physics effects are parametrized by the Standard-Model Effective Field Theory (SMEFT) written in a complete basis of up to dimension-6 operators, we calculate the CP-conserving one-loop amplitude for the decay $h\to \gamma\gamma$ in ...

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

Electroweak Corrections to Higgs to $\gamma\gamma$ and $W^+W^-$ in the SMEFT

, 2018
Higgs decays to gauge boson pairs are a crucial ingredient in the study of Higgs properties, with the decay $H\rightarrow\gamma\gamma$ being particularly sensitive to new physics effects.

Consistent Searches for SMEFT Effects in Non-Resonant Dijet Events

, 2018
We investigate the bounds which can be placed on generic new-physics contributions to dijet production at the LHC using the framework of the Standard Model Effective Field Theory, deriving the first consistently-treated EFT bounds from non-resonant high ...
