A simultaneous fit to multiple ATLAS datasets constrains 48 SMEFT Wilson coefficients and matches subsets to 2HDM and heavy-vector models, finding consistency with the Standard Model.
Phenomenological analysis using NRQCD Green's functions and reweighting shows toponium signals may be detectable in single-leptonic final states with LHC Run 2 data.
Three new physics resonances with top flavor-changing couplings are mapped to SMEFT operators at the electroweak scale and their phenomenology is analyzed.
Higher-order QCD predictions for pp to tW enable three-parameter SMEFT fits that constrain effective new-physics scales to 0.5–2 TeV using LHC Run II and III data.
Excesses in di-photon and other channels at the LHC indicate possible new scalars near 95 GeV and 152 GeV, with the 152 GeV candidate fitting an SU(2)_L triplet model that also affects top-quark distributions.
