In recent years the perturbative approach to the short flow time expansion (STFX) of the gradient flow has been used in a variety of applications, such as meson mixing, for comparison to data from lattice field theory. These computations have usually utilised the method of projectors, which necessitates vanishing quark masses. However, it has been suggested by Hiromasa et. al. that the full...

I will show preliminary results for the complete NLO corrections to the $ pp \to t\bar{t}+X$ process in the lepton+jets decay channel at the Run III energy of $\sqrt{s} = 13.6\,\text{TeV}$ at the LHC. The calculation includes all resonant and non-resonant Feynman diagrams, interference effects, and Breit-Wigner propagators as well as all higher-order QCD and EW effects. The integrated and...

We report on a new framework for multiloop calculations that makes use of FORM and Mathematica. While FORM is employed for computationally heavy tasks such as amplitude evaluation or insertion of reduction tables, less performance-critical such as topology identification and minimization are done with FeynCalc. The interfaces to IBP-Reduction tools such as FIRE or KIRA are handled via the...

We present the program package ${\tt ggxy}$, which in its first version can be used to calculate partonic and hadronic cross sections to Higgs boson pair production at NLO QCD. The 2-loop virtual amplitudes are implemented using analytical approximations in different kinematic regions, while all other parts of the calculation are exact. This implementation allows to freely modify the masses of...
