TL;DR: In this paper, the associated production of a top-quark pair with a W, Z, or Higgs boson at the LHC was studied and predictions for the total cross sections as well as for several differential distributions of the massive particles in the final state were provided.

TL;DR: In this paper, a set of one-loop corrections for vanishing-gauge couplings in the Standard Model effective field theory (SMEFT) is presented. Butler et al. showed that these corrections can be obtained within an extension of the widely used on-shell renormalisation scheme appropriate for SMEFT calculations, and showed explicitly how UV divergent bare amplitudes from a total of 21 different operators are rendered finite within this scheme.

TL;DR: Theresummation effects on the differential distributions are significant, bringing theoretical predictions into better agreement with experimental data compared to fixed-order calculations, and highlighting the importance of all-orders resummation in dedicated studies of boosted top production.

TL;DR: In this paper, the decay rate in the dimension-6 standard model effective field theory (SMEFT) has been investigated and the QCD corrections multiplying the dimension 6 Wilson coefficients at tree-level are proportional to the standard model (SM) ones.

TL;DR: In this article, a set of one-loop corrections to muon decay in the limit of vanishing gauge couplings is presented. But these corrections are restricted to the case where the couplings are fixed.
