The Global and Modular Beyond-the-Standard Model Inference Tool (GAMBIT) is an open-source code for performing the most complete and rigorous assessments possible of new particle physics theories.

This is achieved through large-scale statistical analyses that combine the latest experimental results from the Large Hadron Collider (LHC), dark matter searches, flavour physics, cosmology and neutrino physics. Using the massively parallelized GAMBIT software and cutting-edge optimization methods, these experimental results are compared against theoretical predictions from high-accuracy quantum field theory calculations and simulations.

A number of recent GAMBIT developments have extended our ability to interpret results from the experiments at the LHC: We have added simulations of a large number of current LHC searches for new particles, incorporated simulations of LHC precision measurements, implemented a system for storing more detailed simulation outputs during large parameter scans, and developed a code auto-generation system that enables studies of generic new physics theories.

In this project, we will utilise LUMI Tier-0 computing power to perform world-leading investigations of a diverse set of promising extensions of the Standard Model (SM) of particle physics. For each theory we will map out in high detail the scenarios that predict discoverable collider physics.

The results will be used to define new search and measurement programmes at the LHC experiments to maximise the potential of LHC Run 3, and to guide the development of a physics programme at future colliders.
