A muon collider would enable the big jump ahead in energy reach that is needed for a
fruitful exploration of fundamental interactions. The challenges of producing muon collisions …

We lay out a comprehensive physics case for a future high-energy muon collider, exploring
a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the …

We present the new version of OpenLoops, an automated generator of tree and one-loop
scattering amplitudes based on the open-loop recursion. One main novelty of OpenLoops 2 …

Abstract We present FeynCalc 9.3, a new stable version of a powerful and versatile
Mathematica package for symbolic quantum field theory (QFT) calculations. Some …

We present an update of the Universal FeynRules Output model format, commonly known as
the UFO format, that is used by several automated matrix-element generators and high …

This Report summarizes the results of the activities of the LHC Higgs Cross Section Working
Group in the period 2014–2016. The main goal of the working group was to present the state …

We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a
comprehensive survey of standard model (SM) extensions. LLPs are a common prediction of …

Jet substructure has emerged to play a central role at the Large Hadron Collider (LHC),
where it has provided numerous innovative new ways to search for new physics and to …

In this work we report on a new version of FeynCalc, a Mathematica package widely used in
the particle physics community for manipulating quantum field theoretical expressions and …

The perspective of designing muon colliders with high energy and luminosity, which is being
investigated by the International Muon Collider Collaboration, has triggered a growing …
