abstract
MadGraph 5 is the new version of the MadGraph matrix element generator, written in the Python programming language. It implements a number of new, efficient algorithms that provide improved performance and functionality in all aspects of the program. It features a new user interface, several new output formats including C++ process libraries for Pythia 8, and full compatibility with FeynRules for new physics models implementation, allowing for event generation for any model that can be written in the form of a Lagrangian. MadGraph 5 builds on the same philosophy as the previous versions, and its design allows it to be used as a collaborative platform where theoretical, phenomenological and simulation projects can be developed and then distributed to the high-energy community. We describe the ideas and the most important developments of the code and illustrate its capabilities through a few simple phenomenological examples.

Non-supersymmetric spin-3/2 dark matter with baryon-violating portals can explain the relic abundance through UV and Boltzmann-suppressed freeze-in, with viable parameter space constrained by indirect detection, direct detection, and LHC monojet searches.
Template-Adapted Mixture Model uses many biased simulations for data-driven estimates of signal and background distributions, yielding unbiased signal fraction estimates with well-calibrated uncertainties.
MadGraph5_aMC@NLO automates tree-level, NLO, shower-matched, and merged cross-section computations for collider processes in a unified flexible framework.
A UV-complete neutron portal model dynamically solves the dark matter-baryon coincidence via a supercooled dark confinement transition that generates GeV-scale asymmetric DM and links to observed gravitational waves.
ALPs with LFV couplings above the muon mass threshold can be produced in LFV meson, tau, and gauge boson decays, yielding clean eμ signatures that enable new searches at future experiments.
Projections show the μTRISTAN same-sign muon collider can significantly improve bounds on anomalous quartic gauge couplings via vector boson scattering in multiple final states at 2 and 6 TeV.
In a vector dark matter extension of the Higgs portal, far detectors at colliders can probe otherwise inaccessible parameter space and set novel bounds on the reheating temperature.
A simultaneous fit to multiple ATLAS datasets constrains 48 SMEFT Wilson coefficients and matches subsets to 2HDM and heavy-vector models, finding consistency with the Standard Model.
Future muon colliders can probe Kaluza-Klein excitations of a 5D U(1)_{Lμ-Lτ} gauge boson across MeV to TeV masses with couplings down to 10^{-5}.
DELPHES 3 delivers a modular fast-simulation framework with particle-flow and pile-up features for reconstructing physics objects in collider detector studies.
ATLAS data on eμ invariant mass and angle distributions in 13 TeV collisions are better described by ttbar models that include color-singlet quasi-bound states near threshold, with fits showing over 3 sigma evidence and a cross-section matching dedicated threshold studies.
PYTHIA 8.2 is a mature C++ event generator that combines hard processes, parton showers, multiparton interactions, and string fragmentation into a complete simulation framework for high-energy collisions.
