Abstract We present an update of the Universal FeynRules Output model format, commonly known as UFO that is used by several automated matrix-element generators and high-energy physics software. detail different features have been proposed extensions initial format during last ten years, collect them in current second version we coin Feynman format. Following philosophy UFO, they consist flexible modular additions to address particle decays, custom propagators, form factors, renormalisation...
We provide an overview of the status Monte-Carlo event generators for high-energy particle physics. Guided by experimental needs and requirements, we highlight areas active development, opportunities future improvements. Particular emphasis is given to physics models algorithms that are employed across a variety experiments. These common themes in generator development lead more comprehensive understanding at highest energies intensities, allow be tested against wealth data have been...

We describe the calculation of next-to-next-to-leading order (NNLO) QCD corrections to isolated photon and photon-plus-jet production, discuss how experimental hadron-level definition isolation criteria can be approximated in theoretical parton-level calculation. The NNLO lead a considerable reduction theory uncertainty on predictions, typically less than five per cent, enable an improved description measurements from ATLAS CMS.
We present the next-to-leading order QCD corrections to Higgs boson pair production in vector fusion, including leading operators framework of Effective Field Theory (HEFT). The corresponding calculation is based on an automated interface between Monte Carlo event generator Whizard and one-loop amplitude GoSam. also include non-factorising diagrams Higgs-Strahlung type, thus going beyond structure function approach. find that some constellations anomalous couplings, while being well within...
We generalize the next-to-leading order QCD calculations for decay rates of $h\to gg$ and $h\to\gamma\gamma$ to case anomalous couplings Higgs boson. demonstrate how this computation can be done in a consistent way within framework an electroweak chiral Lagrangian, based on systematic power counting. It turns out that no additional coupling parameters arise at NLO beyond those already present leading order. The impact is large uncertainties from are significantly reduced NLO. only mildly...
A bstract Isolated photons at hadron colliders are defined by permitting only a limited amount of hadronic energy inside fixed-size cone around the candidate photon direction. This isolation criterion admits contributions from collinear radiation off QCD partons and parton-to-photon fragmentation processes. We compute NNLO corrections to isolated photon-plus-jet production, including these two contributions. Our newly derived results allow us reproduce prescription used in experimental...
Isolated photon production at hadron colliders proceeds via direct and fragmentation processes. Theory predictions for the isolated photon-plus-jet cross section often impose idealised isolation criteria, eliminating contribution introducing a systematic uncertainty in comparison to data. We present NNLO with experimental including both, contributions. Predictions two different parton-to-photon functions are compared, allowing an estimation of stemming from only loosely constrained functions.
We give a status report on new developments within the Whizard event generator. Important features comprise NLO electroweak automation (incl. extension to BSM processes like SMEFT), loop-induced and in UFO interface. highlight work progress further plans, such as implementation of PDFs, photon radiation, exclusive top threshold for exotic physics searches.
