We study one-loop effects induced by an anomalous Higgs trilinear coupling on total and differential rates for the \(H\rightarrow 4\ell \) decay and some of the main single-Higgs production channels at the LHC, namely, VBF, VH, \(t{\bar{t}}H\) and tHj. Our results are based on a public code that calculates these effects by simply reweighting samples of Standard-Model-like events...

In this work we present for the first time predictions for top-quark pair differential distributions at the LHC at NNLO QCD accuracy and including EW corrections. For the latter we include not only contributions of \( \mathcal{O}\left({\alpha}_s^2\alpha \right) \), but also those of order \( \mathcal{O}\left({\alpha}_s{\alpha}^2\right) \) and \( \mathcal{O}\left({\alpha}^3\right...

We study the production of a top-quark pair in association with one and two vector bosons, \( t\overline{t}V \) and \( t\overline{t}V\kern0.1em V \) with V = γ, Z, W ±, at the LHC. We provide predictions at next-to-leading order in QCD for total cross sections and top-quark charge asymmetries as well as for differential distributions. A thorough discussion of the residual...

In this paper we discuss the effect of the complete leading-order QED corrections to the DGLAP equations that govern the perturbative evolution of parton distribution functions (PDFs). This requires the extension of the purely QCD DGLAP evolution including a PDF for the photons and, consistently, also for the charged leptons e ±, μ ± and τ ±. We present the implementation of the...

We present the calculation of the electroweak corrections for squark-antisquark pair production at the LHC within the Minimal Supersymmetric Standard Model. Taking into account all possible chirality and light-flavor configurations, we evaluate the NLO EW corrections, which are of \( \mathcal{O}\left({\alpha}_s^2\alpha \right) \), as well as the subleading tree-level...
