Bayesian model selection over SMEFT operator subsets using a genetic algorithm and BIC approximation is applied to electroweak, Higgs, top and diboson data, finding no evidence for new physics and improved Wilson coefficient posteriors compared to global fits.
Two-loop SMEFT RGEs induce non-negligible effects on the evolution of Wilson coefficients, leading to percent-level shifts in projected sensitivities for four-quark, top Yukawa, and Higgs-gluon operators in collider fits.
Computes one-loop mixing of bosonic and two-fermion interactions into two-fermion operators in dim-8 SMEFT, leaving only four-fermion to two-fermion mixing to finish the renormalization program.
High-energy amplitude ratios for longitudinal di-boson production approach unity in the SM and dimension-6 SMEFT but not necessarily in HEFT, making the W±_L Z_L to W±_L h cross section ratio a promising discriminator between linear and non-linear electroweak symmetry at the HL-LHC.
Future e+e- colliders can constrain new physics through precision Higgs and electroweak measurements in Higgs-coupling, EFT, and SMEFT frameworks, with updated SMEFiT code released.
Multijet and VBF processes can constrain directions in the ten-dimensional space of four-light quark operator Wilson coefficients in SMEFT via linear SM interference.
NLO EW corrections to WW production from SMEFT top operators yield competitive sensitivity at LEP3 and FCC-ee relative to ZH production and existing LEP/LHC bounds.
Higgs precision data now meaningfully tightens SMEFT constraints and increases the lower bound on new physics scales across different flavor assumptions.
A one-operator-at-a-time sensitivity analysis identifies the collider observables providing the strongest individual constraints on top-quark SMEFT operators from current and projected data.
